Summaries for MYLK3 Gene

Entrez Gene Summary for MYLK3 Gene

  • Phosphorylation of cardiac myosin heavy chains (see MYH7B, MIM 609928) and light chains (see MYL2, MIM 160781) by a kinase, such as MYLK3, potentiates the force and rate of cross-bridge recruitment in cardiac myocytes (Chan et al., 2008 [PubMed 18202317]).[supplied by OMIM, Jul 2008]

GeneCards Summary for MYLK3 Gene

MYLK3 (Myosin Light Chain Kinase 3) is a Protein Coding gene. Among its related pathways are Regulation of actin cytoskeleton and Immune response CCR3 signaling in eosinophils. GO annotations related to this gene include calmodulin-dependent protein kinase activity and myosin light chain kinase activity. An important paralog of this gene is MYLK4.

UniProtKB/Swiss-Prot for MYLK3 Gene

  • Kinase that phosphorylates MYL2 in vitro. Promotes sarcomere formation in cardiomyocytes and increases cardiomyocyte contractility (By similarity).

Tocris Summary for MYLK3 Gene

  • Myosin Light Chain Kinases (MLCKs) are a group of protein serine/threonine kinases that is currently divided into two subtypes, MLCK1 and MLCK2. MLCK1 is found in smooth muscle and phosphorylates myosin II regulatory light chains at Ser19, allowing myosin crossbridges to bind to actin filaments and initiate contraction. In addition to smooth muscle contraction, MLCK1 is involved in a diverse range of biological processes including control of endothelial and vascular permeability, growth initiation of astrocytes processes, neurotransmitter release in the sympathetic nervous system and apoptosis of fibroblasts. MLCK2 is found in striated muscle and co-localizes with phosphorylated MLC filaments to mediate skeletal and cardiac muscle contraction. MLCK3 and MLCK4 have recently been identified but are yet to be fully characterized. MLCKs are activated by Ca2+-calmodulin complexes and require Mg2+ or Ca2+ as a co-factor.
