REPS2

The product of this gene is part of a protein complex that regulates the endocytosis of growth factor receptors. The encoded protein directly interacts with a GTPase activating protein that functions downstream of the small G protein Ral. Its expression can negatively affect receptor internalization and inhibit growth factor signaling. Multiple transcript variants encoding different isoforms have been found for this gene.

RALBP1 Associated Eps Domain Containing 2

Involved in ligand-dependent receptor mediated endocytosis of the EGF and insulin receptors as part of the Ral signaling pathway (PubMed:9422736, PubMed:12771942, PubMed:10393179).
By controlling growth factor receptors endocytosis may regulate cell survival (PubMed:12771942).
Through ASAP1 may regulate cell adhesion and migration (PubMed:12149250).

Cytoplasm

Tyrosine-phosphorylated upon stimulation of cells with EGF. Phosphorylation on Tyr-residues induces its association with the EGF receptor probably indirectly through an adapter like GRB2.
