Summaries for MYL1 Gene

Entrez Gene Summary for MYL1 Gene

  • Myosin is a hexameric ATPase cellular motor protein. It is composed of two heavy chains, two nonphosphorylatable alkali light chains, and two phosphorylatable regulatory light chains. This gene encodes a myosin alkali light chain expressed in fast skeletal muscle. Two transcript variants have been identified for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for MYL1 Gene

MYL1 (Myosin Light Chain 1) is a Protein Coding gene. Among its related pathways are ERK Signaling and Cytoskeleton remodeling Regulation of actin cytoskeleton by Rho GTPases. Gene Ontology (GO) annotations related to this gene include calcium ion binding and structural constituent of muscle. An important paralog of this gene is MYL4.

UniProtKB/Swiss-Prot for MYL1 Gene

  • Regulatory light chain of myosin. Does not bind calcium.

Tocris Summary for MYL1 Gene

  • Myosins are a large family of motor proteins that share the common features of ATP hydrolysis (ATPase enzyme activity), actin binding and potential for kinetic energy transduction. Originally isolated from muscle cells, almost all eukaryotic cells are known to contain myosins.
