Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Species predicted to react based on 100% sequence homology: Mouse, Rat.
Specificity / Sensitivity
Phospho-LIMK1 (Thr508)/LIMK2 (Thr505) Antibody detects transfected levels of LIMK1 and LIMK2 only when phosphorylated at threonine 508 or 505.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr508 of human LIMK1. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from COS cells, untransfected (lane 1), transfected with Wild-type LIMK1 (lanes 2 and 3) or with LIMK1 T508A mutant (lanes 4 and 5), using Phospho-LIMK1 (Thr508)/LIMK2 (Thr505) Antibody (top), LIMK1 Antibody #3842 (middle) or HA-Tag (262K) mAb #2362 (bottom). Cells were either untreated (lanes 1, 2 and 4) or treated with PMA (lanes 3 and 5). (Triple HA-tagged LIMK1 plasmids kindly provided by Dr. K. Mizuno, Biological Institute, Tohoku University, Japan.)
LIM kinases (LIMK1 and LIMK2) are serine/threonine kinases that have two zinc finger motifs, known as LIM motifs, in their amino-terminal regulatory domains (1). LIM kinases are involved in actin cytoskeletal regulation downstream of Rho-family GTPases, PAKs, and ROCK (2,3). PAK1 and ROCK phosphorylate LIMK1 or LIMK2 at the conserved Thr508 or Thr505 residues in the activation loop, increasing LIMK activity (3-5). Activated LIM kinases inhibit the actin depolymerization activity of cofilin by phosphorylation at the amino-terminal Ser3 residue of cofilin (6,7).
