forkhead associated (FHA) domain found in sarcolemmal membrane-associated protein (SLMAP) and similar proteins
SLMAP, also called sarcolemmal-associated protein (SLAP), is a tail-anchored protein involved in fundamental cellular processes, such as myoblast fusion, cell cycle progression, and chromosomal inheritance. It is a cardiac membrane protein that plays an important role in E-C coupling and the adrenergic response of the heart. Overexpression of the SLMAP gene has been associated with diabetes and endothelial dysfunction of macro- and micro-blood vessels. SLMAP contains an N-terminal FHA domain, which is a small phosphopeptide recognition module.
Comment:also based on structures of other FHA domains with bound phosphopeptide
Comment:GR at the C terminus of strand beta3, SRxH just preceding beta5, and motif SxNG in the beta6-beta7 turn indicate a canonical mode of pThr recognition.
