    Glycosylphosphatidylinositol (GPI)-anchored proteins typically localise to lipid rafts. GPI-anchored protein microdomains may be present in the plasma membrane; however, they have been studied using heterogeneously expressed GPI-anchored proteins, and the two-dimensional distributions of endogenous molecules in the plasma membrane are difficult to determine at the nanometre scale. Here, we used immunoelectron microscopy using a quick-freezing and freeze-fracture labelling (QF-FRL) method to examine the distribution of the endogenous GPI-anchored protein SAG1 in Toxoplasma gondii at the nanoscale. QF-FRL physically immobilised molecules in situ, minimising the possibility of artefactual perturbation. SAG1 labelling was observed in the exoplasmic, but not cytoplasmic, leaflets of T. gondii plasma membrane, whereas none was detected in any leaflet of the inner membrane complex. Point pattern analysis of SAG1 immunogold labelling revealed mostly random distribution in T. gondii plasma membrane. The present method obtains information on the molecular distribution of natively expressed GPI-anchored proteins and demonstrates that SAG1 in T. gondii does not form significant microdomains in the plasma membrane.

    Autophagy is a degradative cellular pathway that protects eukaryotic cells from starvation/stress. Phosphatidylinositol 4-kinases, Pik1p and Stt4p, are indispensable for autophagy in budding yeast, but participation of PtdIns-4 kinases and their product, phosphatidylinositol 4-phosphate [PtdIns(4)P], is not understood. Nanoscale membrane lipid distribution analysis showed PtdIns(4)P is more abundant in yeast autophagosomes in the luminal leaflet than the cytoplasmic leaflet. PtdIns(4)P is confined to the cytoplasmic leaflet of autophagosomal inner and outer membranes in mammalian cells. Using temperature-conditional single PIK1 or STT4 PtdIns 4-kinase mutants, autophagic bodies in the vacuole of PIK1 and STT4 mutant cells dramatically decreased at restrictive temperatures, and the number of autophagosomes in the cytosol of PIK1 mutants cells was also decreased, whereas autophagosome levels of STT4 mutant cells were comparable to that of wild-type and STT4 mutant cells at permissive temperatures. Localization of PtdIns(4)P in the luminal leaflet in the biological membrane is a novel finding, and differences in PtdIns(4)P distribution suggest substantial differences between yeast and mammals. We also demonstrate in this study that Pik1p and Stt4p play essential roles in autophagosome formation and autophagosome-vacuole fusion in yeast cells, respectively.

    TMEM16K, a membrane protein carrying 10 transmembrane regions, has phospholipid scramblase activity. TMEM16K is localized to intracellular membranes, but whether it actually scrambles phospholipids inside cells has not been demonstrated, due to technical difficulties in studying intracellular lipid distributions. Here, we developed a freeze-fracture electron microscopy method that enabled us to determine the phosphatidylserine (PtdSer) distribution in the individual leaflets of cellular membranes. Using this method, we found that the endoplasmic reticulum (ER) of mammalian cells harbored abundant PtdSer in its cytoplasmic leaflet and much less in the luminal leaflet, whereas the outer and inner nuclear membranes (NMs) had equivalent amounts of PtdSer in both leaflets. The ER and NMs of budding yeast also harbored PtdSer in their cytoplasmic leaflet, but asymmetrical distribution in the ER was not observed. Treating mouse embryonic fibroblasts with the Ca2+ ionophore A23187 compromised the cytoplasmic leaflet-dominant PtdSer asymmetry in the ER and increased PtdSer in the NMs, especially in the nucleoplasmic leaflet of the inner NM. This Ca2+-induced PtdSer redistribution was not observed in TMEM16K-null fibroblasts, but was recovered in these cells by reexpressing TMEM16K. These results indicate that, similar to the plasma membrane, PtdSer in the ER of mammalian cells is predominantly localized to the cytoplasmic leaflet, and that TMEM16K directly or indirectly mediates Ca2+-dependent phospholipid scrambling in the ER.

    Phosphatidylinositol 4-phophate (PtdIns(4)P) is an essential signaling molecule in the Golgi body, endosomal system, and plasma membrane and functions in the regulation of membrane trafficking, cytoskeletal organization, lipid metabolism and signal transduction pathways, all mediated by direct interaction with PtdIns(4)P-binding proteins. PtdIns(4)P was recently reported to have functional roles in autophagosome biogenesis. LC3 and GABARAP subfamilies and a small GTP-binding protein, Rab7, are localized on autophagosomal membranes and participate at each stage of autophagosome formation and maturation. To better understand autophagosome biogenesis, it is essential to determine the localization of PtdIns(4)P and to examine its relationship with LC3 and GABARAP subfamilies and Rab7. To analyze PtdIns(4)P distribution, we used an electron microscopy technique that labels PtdIns(4)P on the freeze-fracture replica of intracellular biological membranes, which minimizes the possibility of artificial perturbation because molecules in the membrane are physically immobilized in situ. Using this technique, we found that PtdIns(4)P is localized on the cytoplasmic, but not the luminal (exoplasmic), leaflet of the inner and outer membranes of autophagosomes. Double labeling revealed that PtdIns(4)P mostly colocalizes with Rab7, but not with LC3B, GABARAP, GABARAPL1 and GABARAPL2. Rab7 plays essential roles in autophagosome maturation and in autophagosome-lysosome fusion events. We suggest that PtdIns(4)P is localized to the cytoplasmic leaflet of the autophagosome at later stages, which may illuminate the importance of PtdIns(4)P at the later stages of autophagosome formation.

    Because chemical fixatives like aldehydes do not work on most lipid molecules in the membrane, small-scale lipid distribution cannot be identified by immunoelectron microscopy in cells fixed by conventional methods. Here we describe a method for physically stabilizing membranes through quick-freezing and freeze-fracture replica formation and for specifically labeling gangliosides for electron microscopy. This method enables the ultrahigh-resolution mapping of membrane lipids including gangliosides within the two-dimensional plane of membranes.

    In budding yeast Saccharomyces cerevisiae, PtdIns(4)P serves as an essential signalling molecule in the Golgi complex, endosomal system, and plasma membrane, where it is involved in the control of multiple cellular functions via direct interactions with PtdIns(4)P-binding proteins. To analyse the distribution of PtdIns(4)P in yeast cells at a nanoscale level, we employed an electron microscopy technique that specifically labels PtdIns(4)P on the freeze-fracture replica of the yeast membrane. This method minimizes the possibility of artificial perturbation, because molecules in the membrane are physically immobilised in situ. We observed that PtdIns(4)P is localised on the cytoplasmic leaflet, but not the exoplasmic leaflet, of the plasma membrane, Golgi body, vacuole, and vesicular structure membranes. PtdIns(4)P labelling was not observed in the membrane of the endoplasmic reticulum, and in the outer and inner membranes of the nuclear envelope or mitochondria. PtdIns(4)P forms clusters of <100 nm in diameter in the plasma membrane and vacuolar membrane according to point pattern analysis of immunogold labelling. There are three kinds of compartments in the cytoplasmic leaflet of the plasma membrane. In the present study, we showed that PtdIns(4)P is specifically localised in the flat undifferentiated plasma membrane compartment. In the vacuolar membrane, PtdIns(4)P was concentrated in intramembrane particle (IMP)-deficient raft-like domains, which are tightly bound to lipid droplets, but not surrounding IMP-rich non-raft domains in geometrical IMP-distributed patterns in the stationary phase. This is the first report showing microdomain formations of PtdIns(4)P in the plasma membrane and vacuolar membrane of budding yeast cells at a nanoscale level, which will illuminate the functionality of PtdIns(4)P in each membrane.

    Phosphatidylinositol 4-phosphate (PtdIns(4)P) is the immediate precursor of phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2), which is located on the cytoplasmic leaflet of the plasma membrane and has been reported to possess multiple cellular functions. Although PtdIns(4)P and PtdIns(4,5)P2 have been reported to localize to multiple intracellular compartments and to each function as regulatory molecules, their generation, regulation and functions in most intracellular compartments are not well-defined. To analyze PtdIns(4)P and PtdIns(4,5)P2 distributions, at a nanoscale, we employed an electron microscopy technique that specifically labels PtdIns(4)P and PtdIns(4,5)P2 on the freeze-fracture replica of intracellular biological membranes. This method minimizes the possibility of artificial perturbation, because molecules in the membrane are physically immobilized in situ. Using this technique, we found that PtdIns(4)P was localized to the cytoplasmic leaflet of Golgi apparatus and vesicular-shaped structures. The PtdIns(4,5)P2 labeling was observed in the cytoplasmic leaflet of the mitochondrial inner membrane and vesicular-shaped structures. Double labeling of PtdIns(4)P and PtdIns(4,5)P2 with endosome markers illustrated that PtdIns(4)P and PtdIns(4,5)P2 were mainly localized to the late endosome/lysosome and early endosome, respectively. PtdIns(4)P and PtdIns(4,5)P2 were colocalized in some endosomes, with the two phospholipids separated into distinct microdomains on the same endosomes. This is the first report showing, at a nanoscale, segregation of PtdIns(4)P- and PtdIns(4,5)P2-enriched microdomains in the endosome, of likely importance for endosome functionality.

    Phosphatidylinositol 4-phosphate [PtdIns(4)P] is the immediate precursor of phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2], which is localized to the cytoplasmic leaflet of the plasma membrane and has been reported to possess multiple cell biological functions. Direct evidence showing the distribution of PtdIns(4)P pools at a nanoscale when the plasma membrane PtdIns(4,5)P2 is hydrolyzed by agonist stimulation is lacking. To analyze the distribution of PtdIns(4)P at a nanoscale, we employed an electron microscopy technique that specifically labels PtdIns(4)P on the freeze-fracture replica of the plasma membrane. This method minimizes the possibility of artificial perturbation, because molecules in the membrane are physically immobilized in situ. Using this technique, we observed no PtdIns(4)P in the caveolae of normal cultured human fibroblasts, although PtdIns(4,5)P2 has been shown to be highly concentrated in them in our previous report. When cells were stimulated with angiotensin II, the level of PtdIns(4)P in the undifferentiated membrane transiently decreased to 64.3% at 10s, began to increase at 30s and largely increased to 341.9% at 40s, and then returned to the initial level at 130s after the stimulation. Interestingly, PtdIns(4)P localized at the caveolae at 70 and 130s after the stimulation. These results suggest that the level of the PtdIns(4)P pool in the plasma membrane is sensitive and the distribution of PtdIns(4)P dramatically changes by agonist stimulation, and there are active sites of production or replenishment of PtdIns(4)P at undifferentiated membrane and caveolar areas.

    Phosphatidylinositol 4-kinase IIα (PtdIns4KIIα) localizes to the trans-Golgi network and endosomal compartments and has been implicated in the regulation of endosomal traffic, but the roles of both its enzymatic activity and the site of its action have not been elucidated. This study shows that PtdIns4KIIα is required for production of endosomal phosphatidylinositol 4-phosphate (PtdIns(4)P) on early endosomes and for the sorting of transferrin and epidermal growth factor receptor into recycling and degradative pathways. Depletion of PtdIns4KIIα with small interfering RNA significantly reduced the amount of vesicular PtdIns(4)P on early endosomes but not on Golgi membranes. Cells depleted of PtdIns4KIIα had an impaired ability to sort molecules destined for recycling from early endosomes. We further identify the Eps15 homology domain-containing protein 3 (EHD3) as a possible endosomal effector of PtdIns4KIIα. Tubular endosomes containing EHD3 were shortened and became more vesicular in PtdIns4KIIα-depleted cells. Endosomal PtdIns(4,5)P2 was also significantly reduced in PtdIns4KIIα-depleted cells. These results show that PtdIns4KIIα regulates receptor sorting at early endosomes through a PtdIns(4)P-dependent pathway and contributes substrate for the synthesis of endosomal PtdIns(4,5)P2.
