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.Carlier, M. et al. (1999) J. Biol. Chem. 274, 33827-33830.Arber, S. et al. (1998) Nature 393, 805-809.Yang, N. et al.

Species
Homo Sapiens (Human)
Specificity
The antibody detects endogenous level of cofilin1 only when phosphorylated at tyrosine 139.
Binds to F-actin and exhibits pH-sensitive F-actin depolymerizing activity. Regulates actin cytoskeleton dynamics. Important for normal progress through mitosis and normal cytokinesis. Plays a role in the regulation of cell morphology and cytoskeletal organization. Required for the up-regulation of atypical chemokine receptor ACKR2 from endosomal compartment to cell membrane, increasing its efficiency in chemokine uptake and degradation
Pathway
Regulation of actin cytoskeleton Fc gamma R-mediated phagocytosis
Protein Families
Actin-binding proteins ADF family
Tissue Specificity
Widely distributed in various tissues.

Purification
Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy usi
