Cofilin 2 (muscle) also known as CFL2 is a protein which in humans is encoded by the CFL2 gene.[5][6]

Function

Cofilin is a widely distributed intracellular actin-modulating protein that binds and depolymerizes filamentous F-actin and inhibits the polymerization of monomeric G-actin in a pH-dependent manner.[6] Cofilin-2 is a member of the AC group of proteins that also includes cofilin-1 (CFL1) and destrin (DSTN), all of which regulate actin-filament dynamics.[7][8] The CFL2 gene encodes a skeletal muscle-specific isoform[9] localized to the thin filaments, where it exerts its effect on actin, in part through interactions with tropomyosins.[10]

Clinical significance

Mutations in the CFL2 gene are associated with nemaline myopathy. Deficiency of cofilin-2 may result in reduced depolymerization of actin filaments, causing their accumulation in nemaline bodies, minicores, and, possibly concentric laminated bodies.[11]
