Group:MUZIC:XIN

Xin actin-binding repeat-containing protein 1 (Alternative name: Cardiomyopathy-associated protein 1) is coded by the gene (Synonyms:CMYA1, XIN) and has an actin-binding domain (ABD). It crosslinks actin filaments and participates in anchoring of membrane proteins. Intraexogic splicing leads to a least three different isoforms.

Xin and Mena/VASP colocalize with filamin c in intercalated discs (ICD, structure at the end of the myocytes that transduce force from the myofibrils via the cell membranes to the extracelluar matrix and neighboring cells) in the adult heart ^[1].

Xin directly binds the EVH1 domain proteins Mena and VASP <ref name="pmid16631741">. Xin binds the unique insertion of filamin c containing Ig domain 20. Xin directly binds F-actin <ref name="pmid15454575">.
