The function of DNAH14 (dynein axonemal heavy chain 14, Ensembl gene identifier ENSG00000185842) is as follows. Force generating protein of respiratory cilia. 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. Involved in sperm motility; implicated in sperm flagellar assembly (By similarity). .
