MYL9

Myosin regulatory light polypeptide 9 is a is_associated_with::protein that in humans is encoded by the MYL9 is_associated_with::gene.

Function
is_associated_with::Myosin, a structural component of muscle, consists of two heavy chains and four light chains. The protein encoded by this gene is a myosin light chain that may regulate muscle contraction by modulating the is_associated_with::ATPase activity of myosin heads. The encoded protein binds calcium and is activated by myosin light chain kinase. Two transcript variants encoding different isoforms have been found for this gene.
