MYL12B Human Recombinant produced in E. coli is a single polypeptide chain containing 196 amino acids (1-172) and having a molecular mass of 22.3kDa.MYL12B is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Myosin is composed of 2 nonphosphorylatable alkali light chains, 2 heavy chains and 2 phosphorylatable regulatory light chains. MYL12B is a hexameric ATPase cellular motor protein which controls contraction in smooth muscle and non-muscle cells throµgh phosphorylation by myosin light chain kinase (MLCK). Phosphorylation of myosin regulatory light chains catalyzed by MLCK in the presence of calcium and calmodulin, rises Actin-activated myosin ATPase activity, thus regulating contractile activity.
The MYL12B solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 200mM Nacl, 2mM DTT and 40% glycerol.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
