EPS8 (Epidermal Growth Factor Receptor Pathway Substrate 8) is a Protein Coding gene. Diseases associated with EPS8 include Deafness, Autosomal Recessive 102 and Autosomal Recessive Non-Syndromic Sensorineural Deafness Type Dfnb. Among its related pathways are Development ERBB-family signaling and Tyrosine Kinases / Adaptors. EPS8 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 EPS8 have been observed but have not been thoroughly characterized.
