Epidermal growth factor receptor substrate 15 is a protein that in humans is encoded by the EPS15 gene.[1]


This gene encodes a protein that is part of the EGFR pathway. The protein is present at clathrin-coated pits and is involved in receptor-mediated endocytosis of EGF. Notably, this gene is rearranged with the HRX/ALL/MLL gene in acute myelogeneous leukemias. Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized.[2]

Model organisms[edit]

Model organisms have been used in the study of EPS15 function. A conditional knockout mouse line, called Eps15tm1a(KOMP)Wtsi[7][8] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[9][10][11]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[5][12] Twenty six tests were carried out on mutant mice and one significant abnormality was observed: homozygous mutant animals had a decreased mean corpuscular hemoglobin concentration.[5]
