Protein Information (annotations from UniProt)

Database IDHIV0004729
UniProt IDP42566
Primary gene name(s)EPS15
Synonym gene name(s)AF1P
Protein nameEpidermal growth factor receptor substrate 15
Protein functionInvolved in cell growth regulation. May be involved in the regulation of mitogenic signals and control of cell proliferation. Involved in the internalization of ligand-inducible receptors of the receptor tyrosine kinase, RTK type, in particular EGFR. Plays a role in the assembly of clathrin-coated pits, CCPs. Acts as a clathrin adapter required for post-Golgi trafficking. Seems to be involved in CCPs maturation including invagination or budding. Involved in endocytosis of integrin beta-1, ITGB1 and transferrin receptor, TFR; internalization of ITGB1 as DAB2-dependent cargo but not TFR seems to require association with DAB2. {ECO:0000269|PubMed:16903783, ECO:0000269|PubMed:18362181, ECO:0000269|PubMed:19458185, ECO:0000269|PubMed:22648170}.
Subcellular locationCytoplasm. Cell membrane;
Peripheral membrane protein;
Cytoplasmic side. Membrane, clathrin-coated pit. Note=Recruited to the plasma membrane upon EGFR activation and localizes to coated pits. Colocalizes with UBQLN1 in ubiquitin-rich cytoplasmic aggregates that are not endocytic compartments and in cytoplasmic juxtanuclear structures called aggresomes. {ECO:0000269|PubMed:16159959}.;
SUBCELLULAR LOCATION: Isoform 2: Early endosome membrane {ECO:0000269|PubMed:18362181};
Peripheral membrane protein {ECO:0000269|PubMed:18362181};
Cytoplasmic side {ECO:0000269|PubMed:18362181}. Note=Colocalizes with HGS on bilayered clathrin coats on endosomes.
