Function

[EPN1_RAT] Binds to membranes enriched in phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2). Modifies membrane curvature and facilitates the formation of clathrin-coated invaginations. Regulates receptor-mediated endocytosis.^[1] ^[2] ^[3]

Publication Abstract from PubMed

Epsin (Eps15 interactor) is a cytosolic protein involved in clathrin-mediated endocytosis via its direct interactions with clathrin, the clathrin adaptor AP-2, and Eps15. The NH(2)-terminal portion of epsin contains a phylogenetically conserved module of unknown function, known as the ENTH domain (epsin NH(2)-terminal homology domain). We have now solved the crystal structure of rat epsin 1 ENTH domain to 1.8 A resolution. This domain is structurally similar to armadillo and Heat repeats of beta-catenin and karyopherin-beta, respectively. We have also identified and characterized the interaction of epsin 1, via the ENTH domain, with the transcription factor promyelocytic leukemia Zn(2)+ finger protein (PLZF). Leptomycin B, an antifungal antibiotic, which inhibits the Crm1- dependent nuclear export pathway, induces an accumulation of epsin 1 in the nucleus. These findings suggest that epsin 1 may function in a signaling pathway connecting the endocytic machinery to the regulation of nuclear function.

Epsin 1 undergoes nucleocytosolic shuttling and its eps15 interactor NH(2)-terminal homology (ENTH) domain, structurally similar to Armadillo and HEAT repeats, interacts with the transcription factor promyelocytic leukemia Zn(2)+ finger protein (PLZF).,Hyman J, Chen H, Di Fiore PP, De Camilli P, Brunger AT J Cell Biol. 2000 May 1;149(3):537-46.
