Phospho-EPS15 (Tyr849) Antibody - #AF0058

Involved 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.

Phosphorylation on Tyr-849 is involved in the internalization of EGFR. Not required for membrane translocation after EGF treatment or for targeting to coated pits, but essential for a subsequent step in EGFR endocytosis (By similarity). Phosphorylated on serine upon DNA damage, probably by ATM or ATR.

Ubiquitinated.

Cytoplasm. 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.

Early endosome membrane>Peripheral membrane protein>Cytoplasmic side.
Note: Colocalizes with HGS on bilayered clathrin coats on endosomes.

Ubiquitously expressed.

Interacts with SGIP1. Interacts with HGS; the interaction bridges the interaction of STAM or STAM2 with EPS15. Isoform 2 interacts with HGS and AP2A2. Part of a complex at least composed of EPS15, HGS, and either STAM or STAM2. Binds AP2A2. Interacts with AP2B1; clathrin competes with EPS15. Binds STON2 and EPN1. Interacts (via its SH3-binding sites) with CRK. Interacts with SH3BP4/TTP. Interacts with ERBB2. Interacts with FCHO1. Interacts with FCHO2. Interacts (via EH domains) with DAB2. Interacts (via UIM repeats) with CORO7 (when ubiquitinated at 'Lys-472'). Interacts (via UIM domains) with UBQLN1 (via ubiquitin-like domain) and can interact with both the ubiquitinated and the non-ubiquitinated forms of UBQLN1. Interacts with UBQLN2 (By similarity).

(Microbial infection) Interacts with vaccinia virus protein A36.

The EH domain interacts with Asn-Pro-Phe (NPF) motifs of target proteins.

The UIM (ubiquitin-interacting motif) repeats specifically bind 'Lys-33'-linked ubiquitin.
