The function of DNAH7 (dynein axonemal heavy chain 7, ENSG00000118997) is as follows. Force generating protein that plays an important role in respiratory cilia and sperm flagella beating (PubMed:34476482). Produces force towards the minus ends of microtubules. Dynein has ATPase activity; the force-producing power stroke is thought to occur on release of ADP (By similarity). {ECO:0000250, ECO:0000269|PubMed:34476482}.
