Disease

[EPS15_HUMAN] Note=A chromosomal aberration involving EPS15 is found in acute leukemias. Translocation t(1;11)(p32;q23) with MLL/HRX. The result is a rogue activator protein.

Function

[EPS15_HUMAN] 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). 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.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Eps15 homology (EH) domains are protein interaction modules that recognize Asn-Pro-Phe (NPF) motifs in their biological ligands to mediate critical events during endocytosis and signal transduction. To elucidate the structural basis of the EH-NPF interaction, the solution structures of two EH-NPF complexes were solved using NMR spectroscopy. The first complex contains a peptide representing the Hrb C-terminal NPFL motif; the second contains a peptide in which an Arg residue substitutes the C-terminal Leu. The NPF residues are almost completely embedded in a hydrophobic pocket on the EH domain surface and the backbone of NPFX adopts a conformation reminiscent of the Asx-Pro type I beta-turn motif. The residue directly following NPF is crucial for recognition and is required to complete the beta-turn. Five amino acids on the EH surface mediate specific recognition of this residue through hydrophobic and electrostatic contacts. The complexes explain the selectivity of the second EH domain of Eps15 for NPF over DPF motifs and reveal a critical aromatic interaction that provides a conserved anchor for the recognition of FW, WW, SWG and HTF ligands by other EH domains.

Molecular mechanism of NPF recognition by EH domains.,de Beer T, Hoofnagle AN, Enmon JL, Bowers RC, Yamabhai M, Kay BK, Overduin M Nat Struct Biol. 2000 Nov;7(11):1018-22. PMID:11062555^[5]
