Force generating protein required for cilia beating in respiratory epithelia (By similarity). Produces force towards the minus ends of microtubules (By similarity). Key component of dynein, a family of motor proteins essential for movement along microtubules (By similarity). Dynein has ATPase activity; the force-producing power stroke is thought to occur on release of ADP (By similarity). Required for structural and functional integrity of cilia (By similarity). . This is the function of Ensembl gene identifier ENSG00000105877 (DNAH11, dynein axonemal heavy chain 11).
