| Short Name | Sprouty |
| description | Sprouty (Spry) and Spred (Sprouty related EVH1 domain) proteins have been identified as inhibitors of the Ras/mitogen-activated protein kinase(MAPK) cascade, a pathway crucial for developmental processes initiated by activation of various receptor tyrosine kinases [, ]. These proteins share a conserved, C-terminal cysteine-rich region, the SPR domain. This domain has been defined as a novel cytosol to membrane translocation domain [, , , ]. It has been found to be a PtdIns(4,5)P2-binding domain that targets the proteins to a cellular localization that maximizes their inhibitory potential [, ]. It also mediates homodimer formation of these proteins [, ].The SPR domain can occur in association with the WH1 domain (see ) (located in the N-terminal part of the proteins) in the Spred proteins. |
