Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
Phospho-Cofilin (Ser3) (77G2) Rabbit mAb detects endogenous levels of cofilin only when phosphorylated at serine 3.
Source / Purification
Monoclonal antibodies are produced by immunizing rabbits with a synthetic phospho-peptide (KLH-coupled) corresponding to residues surrounding Ser3 of human cofilin.
Western Blotting
Western blot analysis of extracts from untreated or λ-phosphatase-treated COS and HeLa cells, using Phospho-Cofilin (Ser3) (77G2) Rabbit mAb.
IF-IC
Confocal immunofluorescent analysis of MCF-7 cells either untreated (left) or lambda-phosphatase treated (right), using Phospho-Cofilin (Ser3) (77G2) Rabbit mAb (green). Blue pseudocolor = DRAQ5™ (fluorescent DNA dye).
Background
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).
