| Primary Identifier | IPR039801 | Type | Family |
| Short Name | EPS8-like |
| description | This entry includes EPS8 and EPS8L1-3 from animals.Epidermal growth factor receptor kinase substrate 8 (EPS8) is a signalling adapter that possesses actin binding, bundling, and barbed-end capping activities []. It forms a complex with Sos-1, Abi1 and the lipid kinase phosphoinositide 3-kinase (PI3-K) to regulate Rac activation that leads to actin cytoskeletal remodeling []. It is critical for dendritic cell migration []. It is involved in the initial growth of stereocilia in both inner hair cells and outer hair cells []. It also regulates axonal filopodia in hippocampal neurons in response to brain-derived neurotrophic factor (BDNF) []. It has been linked to proliferation, metastasis and prognosis of many malignant tumours [].Similarly to EPS8, EPSLs interact with Abi1 and Sos-1. However, only EPS8L1 and EPS8L2 activate the Rac-GEF activity of Sos-1, and bind to actin in vivo []. Eps8L2 null-mutant mice has been shown to exhibit a late-onset, progressive hearing loss that is directly linked to a gradual deterioration in hair bundle morphology []. |
