Protein kinase C and ROC Kinase are involved in regulating Calcium ion intake; these Calcium ions, in turn stimulate a MYLK, forcing a contraction. [9] Rho kinase also modulates the activity of MYLK by downregulating the activity of MYLK's counterpart protein: Myosin Light Chain Phosphatase (MYLP). [10]
This gene, a muscle member of the immunoglobulin superfamily, encodes a myosin light-chain kinase, which is a calcium-/calmodulin-dependent enzyme.This kinase phosphorylates myosin regulatory light chains to facilitate myosin interaction with actin filaments to produce contractile activity.
Telokin's systematic name is ATP:[myosin light chain] O-phosphotransferase and its recommended name is myosin-light-chain kinase. (EC 2.7.11.18). The gene MYLK, a muscle member of the immunoglobulin gene superfamily, encodes myosin light chain kinase which is a calcium/calmodulin dependent enzyme. Four transcript variants that produce four ...
Structurally, myosin light chains belong to the EF-hand family, a large family of Ca 2+ - binding proteins. MLCs contain two Ca 2+ - binding EF-hand motifs. MLCs isoforms modulate the Ca 2+ of force transduction and cross-bridge kinetics. Myosin light chains (MLCs) can be broadly classified into two groups: Essential or alkali MLC (MLC1 or ELC),
Myosin light chain kinase 4 also known as MYLK4 is an enzyme which in humans is encoded by the MYLK2 gene. [2] MYLK4 is a member of the myosin light-chain kinase family of serine/threonine-specific protein kinases that phosphorylate the regulatory light chain of myosin II.

In smooth muscle, a single gene [20]) codes for the heavy chains myosin II, but splice variants of this gene result in four distinct isoforms. [19] It also contains 4 myosin light chains (MLC), resulting in 2 per head, weighing 20 (MLC 20) and 17 (MLC 17) kDa. [19] These bind the heavy chains in the "neck" region between the head and tail.
Specialized CaM kinases, such as the myosin light chain kinase that phosphorylates myosin, causing smooth muscles to contract. Multifunctional CaM kinases, also collectively called CaM kinase II, which play a role in neurotransmitter secretion, transcription factor regulation, and glycogen metabolism.
