This enzyme belongs to the family of transferases, specifically those transferring a phosphate group to the sidechain oxygen atom of serine or threonine residues in proteins (protein-serine/threonine kinases). The systematic name of this enzyme class is ATP:[myosin heavy-chain] O-phosphotransferase. Other names in common use include

ATP:myosin-heavy-chain O-phosphotransferase
calmodulin-dependent myosin heavy chain kinase
MHCK
MIHC kinase
myosin heavy chain kinase
myosin I heavy-chain kinase
myosin II heavy-chain kinase
[myosin-heavy-chain] kinase
myosin heavy chain kinase A
STK6.
