Anti-phospho Cofilin-1 Antibody (Ser3)

产品说明

一般描述

Cofilin-1 (UniProt P23528; also known as 18 kDa phosphoprotein, Cofilin non-muscle isoform, p18) is encoded by the CFL1 (also known as CFL) gene (Gene ID 1072) in human. Cofilin-1 (non-muscle cofilin), cofilin-2 (muscle cofilin), and actin-depolymerizing factor (ADF) play an essential role in regulating actin filament dynamics and reorganization by stimulating the severance and depolymerization of actin filaments. The three cofilin family members share 70% to 81% sequence identity, exhibit similar biological functions, and display distinct but overlapping expression patterns. Cofilins and ADF bind actin monomers and filaments (G-actin and F-actin) and increase the number of actin monomers and filament fragments, facilitating filament turnover and treadmilling at key locations in migrating cells. Cofilins and ADF are inactivated by phosphorylation at Ser3 by LIM-kinases (LIMKs) and testicular protein kinases (TESKs) and are reactivated by dephosphorylation by the slingshot (SSH) family of protein phosphatases and chronophin. Cfl1-knockout results in mouse embryonic lethality at E11.5 12.5 due to aberrant neural tube closure and defective neural crest cell migration, while Adf-deficient mice are viable with normal brain appearance, but suffer from corneal defects that cause blindness in adult mice.

特异性

Target band detection by this polyclonal antibody was prevented by preblocking with the immunogen phosphopeptide, but not the corresponding non-phosphopeptide.

免疫原

KLH-conjugated linear peptide corresponding to the N-termnal sequence of human cofilin-1 with phosphorylated Ser3.

应用

Research Category
Cell Structure
This rabbit polyclonal Anti-phospho Cofilin-1 (Ser3), Cat. No. AB3831-I is validated for use in Peptide Inhibition Assay and Western Blotting for the detection of Cofilin-1 Ser3 phosphorylation.
Peptide Inhibition Assay: Target band detection in 10 µg of HeLa cell lysate was prevented by preblocking a representative lot with the immunogen phosphopeptide, but not the corresponding non-phosphopeptide.
