Kinaza teškog lanca miozina (EC 2.7.11.7, ATP:miozin-teški lanac O-fosfotransferaza, kalmodulin-zavisni miozin teški lanac kinaza, MHCK, MIHC kinaza, miozin teški lanac kinaza, miozin I teški-lanac kinaza, miozin II teški-lanac kinaza, (miozin-teški-lanac) kinaza, miozin teški lanac kinaza A, STK6) je enzim sa sistematskim imenom ATP:(miozin teškog lanca) O-fosfotransferaza.[1][2][3][4][5][6][7][8][9] Ovaj enzim katalizuje sledeću hemijsku reakciju

ATP + [miozin teškog lanca] ADP + [miozin teškog lanca] fosfat

Enzim iz Dictyostelium sp. (sluzave plesni) fosforiliše teške lance Dictyostelium miozin, čime inhibira aktinom aktiviranju ATPaznu aktivnost miozina.
