1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
機能May 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.
配列類似性Belongs to the sorting nexin family. Contains 1 BAR domain. Contains 1 PX (phox homology) domain. Contains 1 SH3 domain.
ドメインThe 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.
翻訳後修飾Ubiquitinated by ITCH. Phosphorylated on tyrosine residues by TNK2. Phosphorylation promotes its activity in the degradation of EGFR.
細胞内局在Cytoplasmic 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.
