  • FunctionMay be involved in several stages of intracellular trafficking. Plays a role in endocytosis via clathrin-coated pits, but also clathrin-independent, actin-dependent fluid-phase endocytosis. Plays a role in macropinocytosis. Promotes internalization of TNFR. Promotes degradation of EGFR after EGF signaling. Stimulates the GTPase activity of DNM1. Promotes DNM1 oligomerization. Promotes activation of the Arp2/3 complex by WASL, and thereby plays a role in the reorganization of the F-actin cytoskeleton. Binds to membranes enriched in phosphatidylinositol 4,5-bisphosphate and promotes membrane tubulation. Has lower affinity for membranes enriched in phosphatidylinositol 3-phosphate.
  • Sequence similaritiesBelongs to the sorting nexin family.
    Contains 1 BAR domain.
    Contains 1 PX (phox homology) domain.
    Contains 1 SH3 domain.
  • DomainThe PX domain mediates interaction with membranes enriched in phosphatidylinositol phosphate. Has high affinity for phosphatidylinositol-4,5-bisphosphate, but can also bind to membranes enriched in other phosphatidylinositol phosphates.
  • Post-translational
    modifications
    Ubiquitinated by ITCH.
    Phosphorylated on tyrosine residues by TNK2. Phosphorylation promotes its activity in the degradation of EGFR.
  • Cellular localizationCytoplasmic vesicle membrane. Cell membrane. Cytoplasmic vesicle > clathrin-coated vesicle. Golgi apparatus > trans-Golgi network. Cell projection > ruffle. Cytoplasm. Localized at sites of endocytosis at the cell membrane. Detected on newly formed macropinosomes. Transiently recruited to clathrin-coated pits at a late stage of clathrin-coated vesicle formation. Colocalizes with the actin cytoskeleton at the cell membrane.
