Cofilin and ADF (actin-depolymerization factor) are members of a family of essential conserved small actin-binding proteins that play pivotal roles in cytokinesis, endocytosis, embryonic development, stress response and tissue regeneration (1). In response to stimuli, cofilin promotes the regeneration of actin filaments by severing preexisting filaments (2). The severing activity of cofilin is inhibited by LIMK or TESK phosphorylation at Ser3 of cofilin (3-5). Phosphorylation at Ser3 also regulates cofilin translocation from the nucleus to the cytoplasm (6).Phospho-Cofilin (Ser3) Antibody detects endogenous levels of cofilin only when phosphory¬lated at Ser3. The antibody may cross-react with phosphory¬lated cofilin 2, the muscle isoform.

Western blot analysis of extracts from asynchronous or mi¬totic C6, CHO and COS cells using Phospho-Cofilin (Ser3) Antibody (upper) or Cofilin Antibody (lower).


Western blot analysis of extracts from HeLa cells, untreated or H2O2-treated using Phospho-Cofilin (Ser3) Antibody (A and B) or Cofilin Antibody (C and D). Membranes (B and D) were treated with alkaline phosphatase (CIP) to demonstrate the phospho-specificity the antibody
