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.

Sequence Annotation

Template:STRUCTURE 3hop Filamin A (FLNA) has an actin-binding domain (ABD). It crosslinks actin filaments and participates in anchoring of membrane proteins. Filamin B (FLNB) is a human cytoplasmic protein which functions similarly to FLNA and guides proper skeletal development. Filamin C (FLNC) is functionally similar and contains 3 domains: the N-terminal ABD, the C-terminal dimerization domain (DD) and a membrane glycoprotein-binding domain. The images at the left and at the right correspond to one representative filamin structure, i.e. the crystal structure of human filamin A (3hop), it forms a ^[1].
