Summaries for MYL3 Gene

Entrez Gene Summary for MYL3 Gene

  • MYL3 encodes myosin light chain 3, an alkali light chain also referred to in the literature as both the ventricular isoform and the slow skeletal muscle isoform. Mutations in MYL3 have been identified as a cause of mid-left ventricular chamber type hypertrophic cardiomyopathy. [provided by RefSeq, Jul 2008]

GeneCards Summary for MYL3 Gene

MYL3 (Myosin Light Chain 3) is a Protein Coding gene. Diseases associated with MYL3 include Cardiomyopathy, Hypertrophic, 8 and Cardiomyopathy, Familial Hypertrophic. Among its related pathways are Sertoli-Sertoli Cell Junction Dynamics and Blood-Brain Barrier and Immune Cell Transmigration: VCAM-1/CD106 Signaling Pathways. 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 MYL3 Gene

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

Tocris Summary for MYL3 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.

  • Cardiomyopathy, familial hypertrophic 8 (CMH8) [MIM:608751]: A hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death. Rarely, patients present a variant of familial hypertrophic cardiomyopathy, characterized by mid-left ventricular chamber thickening. {ECO:0000269 PubMed:12021217, ECO:0000269 PubMed:12707239, ECO:0000269 PubMed:23594557, ECO:0000269 PubMed:8673105}.
