| Primary Identifier | IPR035462 | Type | Domain |
| Short Name | Eps8_SH3 |
| description | This entry represents the SH3 domain found in Eps8 and Eps8-like proteins including Eps8-like 1-3. These proteins contain N-terminal phosphotyrosine-binding (PTB), central SH3, and C-terminal effector domains. The SH3 domains of Eps8 and similar proteins recognize peptides containing a PxxDY motif, instead of the classical PxxP motif []. 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 []. |
