ANTI-EPS8

Description_x000D_ General description_x000D_ This gene encodes a member of the EPS8 family. This protein contains one PH domain and one SH3 domain. It functions as part of the EGFR pathway, though its exact role has not been determined. Highly similar proteins in other organisms are involved in the transduction of signals from Ras to Rac and growth factor-mediated actin remodeling. Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized.

In addition, it also interacts with the Src non-receptor tyrosine kinase. The protein is involved in Rac signaling and receptor endocytosis. It also regulates dendritic cell migration, morphogenesis of intestinal cells and microvilli, and stereocilia activity. It is upregulated in pancreatic cancer and oral squamous cell carcinoma. Mutation in EPS8 is associated with autosomal recessive profound deafness.
