PFAM accession number:PF08043
Interpro abstract (IPR012510):

The repeat has the consensus sequence GDV(K/Q/R)(T/S/G)X(R/K/T) WLFETXPLD. This repeat motif is typically found in the N terminus of the proteins, with a copy number between 2 and 28 repeats. Direct evidence for binding to and stabilising F-actin has been found in the human protein (Q702N9) [(PUBMED:16631741)]. The homologues in mouse and chicken localise in the adherens junction complex of the intercalated disc in cardiac muscle and in the myotendon junction of skeletal muscle. mXin may co-localise with Vinculin which is known to attach the actin to the cytoplasmic membrane [(PUBMED:16631741)]. It has been shown that the amino-terminus of human xin (CMYA1) binds the EVH1 domain of Mena/VASP/EVL, and the carboxy-terminus binds the, for the filamin family unique, domain 20 of filamin C [(PUBMED:12203715)]. This confirms the proposed role of xin repeat containing proteins as F-actin-binding adapter proteins.
