Gene

• Entrez ID: 57644
• Gene name: Myosin heavy chain 7B
• Gene symbol: MYH7B
• Synonyms (NCBI Gene): MHC14, MYH14, lncMYH7b
• Chromosome: 20
• Chromosome location: 20q11.22
• Summary: The myosin II molecule is a multi-subunit complex consisting of two heavy chains and four light chains. This gene encodes a heavy chain of myosin II, which is a member of the motor-domain superfamily. The heavy chain includes a globular motor domain, whic
