cofilin

Function: - cofilin has weak F-actin severing activity - binds to actin monomers. - appears to 'nibble' monomer from F-actin leaving free barbed end - action similar to destrin - phospholipid binding may reduce affinity for G-actin [1] - phosphorylation deactivates cofilin; dephosphorylation activates - phosphorylated by LIMK1 - dephosphorylated by SSH2, SSH3
