Protein Function and Prediction

The Xirp2 gene encodes two isoforms of a protein that protects actin filaments from depolymerization. Studies have shown that XIRP2 (alternatively, cardiomyopathy associated gene 3; CMYA3), a member of the actin-binding Xin gene family, is an effector of angiogensin II signaling in the heart (1-3). Isoform 1 is 3784 amino acids long. The protein interacts with ACTN2 and F-actin. Protein expression is restricted to heart and skeletal muscle. The protein contains a LIM zinc-binding domain at amino acids 3255-3315 and 28 actin-binding Xin repeats (Uniprot Q4U4S6). Homozygous null mice have an abnormal heart shape, ventricular septal defects, a failure of mature intercalated disc formation, severe growth retardation, and postnatal lethality.

Expression/Localization

EST analysis has determined that XIRP2 is expressed in heart, tongue, and skeletal muscle (2). Another study using Northern blot analysis determined that XIRP2 in expressed in heart and skeletal muscle only (4). XIRP2 protein has been confirmed in striated muscle; immunohistochemistry revealed a striated pattern in mouse heart and colocalization with alpha-actinin-2 at Z discs and intercalated disk (4;5).

Background
