CC -!- FUNCTION: Involved in several stages of intracellular trafficking.
CC Interacts with membranes containing phosphatidylinositol lipids. Acts
CC in part as component of the retromer membrane-deforming SNX-BAR
CC subcomplex. The SNX-BAR retromer mediates retrograde transport of cargo
CC proteins from endosomes to the trans-Golgi network (TGN) and is
CC involved in endosome-to-plasma membrane transport for cargo protein
CC recycling. The SNX-BAR subcomplex functions to deform the donor
CC membrane into a tubular profile called endosome-to-TGN transport
CC carrier (ETC). Does not have in vitro vesicle-to-membrane remodeling
CC activity. Involved in retrograde transport of lysosomal enzyme receptor
CC IGF2R. May function as link between endosomal transport vesicles and
CC dynactin. Plays a role in the internalization of EGFR after EGF
CC stimulation. Involved in EGFR endosomal sorting and degradation; the
CC function involves PIP5K1C and is retromer-independent. Together with
CC PIP5K1C facilitates HGS interaction with ubiquitinated EGFR, which
CC initiates EGFR sorting to intraluminal vesicles (ILVs) of the
CC multivesicular body for subsequent lysosomal degradation. Involved in
CC E-cadherin sorting and degradation; inhibits PIP5K1C-mediated E-
CC cadherin degradation. Plays a role in macropinocytosis (By similarity).
CC {ECO:0000250|UniProtKB:Q9Y5X3}.
CC -!- SUBUNIT: Forms heterodimers with BAR domain-containing sorting nexins
CC SNX1 and SNX2; does not homodimerize. The heterodimers are proposed to
CC self-assemble into helical arrays on the membrane to stabilize and
CC expand local membrane curvature underlying endosomal tubule formation.
CC Thought to be a component of the originally described retromer complex
CC (also called SNX-BAR retromer) which is a pentamer containing the
CC heterotrimeric retromer cargo-selective complex (CSC), also described
CC as vacuolar protein sorting subcomplex (VPS), and a heterodimeric
CC membrane-deforming subcomplex formed between SNX1 or SNX2 and SNX5 or
CC SNX6 (also called SNX-BAR subcomplex); the respective CSC and SNX-BAR
CC subcomplexes associate with low affinity. Interacts with SNX1, SNX2,
CC VPS26A, VPS29, VPS35, DCTN1, DOCK1, MIB1, PIP5K1C. Interacts with HGS;
CC increased by PIP5K1C kinase activity and by PtdIns(3P) and/or
CC PtdIns(3,4)P2 (By similarity). {ECO:0000250|UniProtKB:Q9Y5X3}.
CC -!- SUBCELLULAR LOCATION: Endosome {ECO:0000250|UniProtKB:Q9Y5X3}. Early
CC endosome {ECO:0000250|UniProtKB:Q9Y5X3}. Early endosome membrane
CC {ECO:0000250|UniProtKB:Q9Y5X3}; Peripheral membrane protein;
CC Cytoplasmic side. Cell membrane {ECO:0000250|UniProtKB:Q9Y5X3};
CC Peripheral membrane protein; Cytoplasmic side
CC {ECO:0000250|UniProtKB:Q9Y5X3}. Cytoplasmic vesicle membrane;
CC Peripheral membrane protein; Cytoplasmic side. Cytoplasm. Cell
CC projection, phagocytic cup. Cell projection, ruffle. Note=Recruited to
CC the plasma membrane after EGF stimulation, which leads to increased
CC levels of phosphatidylinositol 3,4-bisphosphate (PdtIns(3,4)P2).
CC Detected on macropinosomes. Targeted to membrane ruffles in response to
CC EGFR stimulation (By similarity). {ECO:0000250|UniProtKB:Q9Y5X3}.
CC -!- DOMAIN: The PX domain mediates interaction with membranes enriched in
CC phosphatidylinositol 3,4-bisphosphate and/or phosphatidylinositol 4,5-
CC bisphosphate. {ECO:0000250}.
CC -!- DOMAIN: The BAR domain is able to sense membrane curvature upon
CC dimerization. Membrane remodeling seems to implicate insertion of an
CC amphipathic helix (AH) in the membrane (By similarity).
CC {ECO:0000250|UniProtKB:Q9Y5X3}.
CC -!- SIMILARITY: Belongs to the sorting nexin family. {ECO:0000305}.
CC -!- CAUTION: The selectivity for particular phosphatidylinositol lipids is
CC under debate. According to one report (PubMed:19553671), the rat
CC protein binds exclusively to phosphatidylinositol 4,5-bisphosphate,
CC while the human protein has been reported (PubMed:15561769) to bind to
CC phosphatidylinositol 3,4-bisphosphate and also to phosphatidylinositol
CC 3-phosphate. {ECO:0000305}.
