Myl9, 1-172aa, Mouse, His tag, E.coli

Myl9 also known as myosin regulatory light polypeptide 9 is one of the numerous regulatory myosin light chains. Regulatory myosin light chains regulate contraction in smooth muscle and non-muscle cells via phosphorylation by myosin light chain kinase (MLCK). Phosphorylation of regulatory myosin light chains is catalyzed by MLCK in the presence of calcium and calmodulin and it increases the actin-activated myosin ATPase activity, thereby regulates the contractile activity. Recombinant mouse Myl9 was expressed in E.coli and purified by using conventional chromatography techniques.
