Overview
| Product Description | Rabbit Polyclonal antibody recognizes Cofilin phospho (Ser3) |
|---|---|
| Tested Reactivity | Hu, Ms, Rat, Chk |
| Tested Application | ELISA, ICC/IF, WB |
| Specificity | This antibody was cross-adsorbed to unphosphorylated Coflin 1 peptide then affinity purified using phospho-Cofilin 1 (Ser-3) peptide (without carrier). The antibody detects a ~19 kDa protein corresponding to the molecular mass of phosphorylated Cofilin 1 on SDS-PAGE immunoblots of Jurkat cells. This band can be removed by lambda phosphatase treatment. |
| Host | Rabbit |
| Clonality | Polyclonal |
| Target Name | Cofilin |
| Antigen Species | Human |
| Immunogen | KLH-conjugated phosphospecific peptide around Ser3 in human Cofilin 1 protein. This sequence has 100% homology with similar regions of rat and mouse Cofilin 1, and has two amino acid differences from human Cofilin 2. |
| Conjugation | Un-conjugated |
| Alternate Names | CFL; 18 kDa phosphoprotein; Cofilin, non-muscle isoform; HEL-S-15; p18; cofilin; Cofilin-1 |

| Gene Symbol | CFL1 |
| Gene Full Name | cofilin 1 (non-muscle) |
| Background | Members of the ADF/cofilin (AC) family are actin-severing proteins that regulate actin remodeling during cellular events such as cell migration, cytokinesis, phagocytosis, endocytosis, axon development, and immune cell activation. In mammals, there are three members of the AC family, muscle-specific cofilin (Cofilin 2), non-muscle cofilin (Cofilin 1), and ADF. In humans, cofilin 1 and ADF have 72% identity, with the major amino acid differences found in the C-terminal region. Regulation of cofilin activity can occur through serine phosphorylation. Activation of cofilin kinases, LIMK1 or LIMK2, leads to phosphorylation of cofilin at serine 3. This phosphorylation disrupts cofilin binding to actin in vitro and in vivo. Multiple phosphatases, PP1, PP2A, PP2B, slingshot, and chronophin can dephosphorylate Ser-3 and activate actin binding. Thus, Ser-3 phosphorylation is a major site for the regulation of cofilin activity. |
| Function | 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. [UniProt] |
| Research Area | Cancer antibody; Cell Biology and Cellular Response antibody; Controls and Markers antibody; Neuroscience antibody; Signaling Transduction antibody |
| Calculated MW | 19 kDa |
| PTM | Inactivated by phosphorylation on Ser-3. Phosphorylated on Ser-3 in resting cells (By similarity). Dephosphorylated by PDXP/chronophin; this restores its activity in promoting actin filament depolymerization. The phosphorylation of Ser-24 may prevent recognition of the nuclear localization signal (By similarity). Phosphorylated via a ARRB1-RAC1-LIMK1-PAK1 cascade upon active ligand stimulation of atypical chemokine receptor ACKR2. |
