Description: Two LIM motif-containing protein kinases (LIMK) have been identified, LIMK1 and LIMK2. These kinases contain two N-terminal LIM domains, a central PDZ domain, and a C-terminal Ser/Thr kinase domain. LIMK1 is highly expressed in brain, heart, and skeletal muscle, while LIMK2 exhibits the highest expression in placenta, liver, lung, kidney, and pancreas. LIMK1 is localized to the actin cytoskeleton and phosphorylates the actin binding/depolymerizing factor, cofilin. During Rho-induced neurite retraction, activation of ROCK leads to LIMK1 activation via phosphorylation at Thr508. In COS-7 cells, disruption of the second LIM domain or the PDZ domain increases LIMK1-induced aggregation of the actin cytoskeleton. In addition, a 32 kDa splice variant that contains only the N-terminus (dLIMK1) suppresses LIMK1 activity by interaction with the C- terminal kinase domain. In humans, deletion of LIMK1 has been implicated in Williams syndrome, a disorder that produces a distinct cognitive profile and vascular disease. Thus, LIMK1, and its splice variant dLIMK1, are thought to have important roles in the regulation of the actin cytoskeleton in a wide varitey of tissues.

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
