Gene Gene information from NCBI Gene database.
Entrez ID 4633
Gene name Myosin light chain 2
Gene symbol MYL2
Synonyms (NCBI Gene)
CMH10MFM12MLC-2MLC-2s/vMLC-2vMLC2
Chromosome 12
Chromosome location 12q24.11
Summary Thus gene encodes the regulatory light chain associated with cardiac myosin beta (or slow) heavy chain. Ca+ triggers the phosphorylation of regulatory light chain that in turn triggers contraction. Mutations in this gene are associated with mid-left ventr
