Controls reversibly actin polymerization and depolymerization in a pH-sensitive manner. It has the ability to bind G- and F-actin in a 1:1 ratio of cofilin to actin. It is the major component of intranuclear and cytoplasmic actin rods.
Isoform CFL2b is expressed predominantly in skeletal muscle and heart. Isoform CFL2a is expressed in various tissues.
Involvement in disease
Defects in CFL2 are the cause of nemaline myopathy type 7 (NEM7) [MIM:610687]. A form of nemaline myopathy. Nemaline myopathies are muscular disorders characterized by muscle weakness of varying severity and onset, and abnormal thread-or rod-like structures in muscle fibers on histologic examination. Nemaline myopathy type 7 presents at birth with hypotonia and generalized weakness. Major motor milestones are delayed, but independent ambulation is achieved.
Belongs to the actin-binding proteins ADF family. Contains 1 ADF-H domain.
The phosphorylation of Ser-24 may prevent recognition of the nuclear localization signal.
