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 [1,2]. 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 [1,2,3,4]. 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 [5,6]. It also mediates homodimer formation of these proteins [1,5].
The SPR domain can occur in association with the WH1 domain (see <PDOC50229>) (located in the N-terminal part of the proteins) in the Spred proteins.
We developed a profile that spans the entire SPR domain.
Note:The SPR domain is also named Spry translocation domain (SpryTD).
