Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

Phospho-LIMK1 (Thr508)/LIMK2 (Thr505) Antibody detects transfected levels of LIMK1 and LIMK2 only when phosphorylated at threonine 508 or 505.

Species Reactivity:

Human

Species predicted to react based on 100% sequence homology

Mouse, Rat

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.

Background

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).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Western Blotting Image 1: Phospho-LIMK1 (Thr508)/LIMK2 (Thr505) Antibody Expand Image
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.)
