Xin repeat
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 stabilizing F-actin has been found in the human protein XIRP1. The homologs in mouse and chicken localize in the adherens junction complex of the intercalated disc in cardiac muscle and in the myotendon junction of skeletal muscle. mXin may co-localize with Vinculin which is known to attach the actin to the cytoplasmic membrane. 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 filaminC. This confirms the proposed role of xin repeat containing proteins as F-actin-binding adapter proteins.
