The function of ODAD4 (outer dynein arm docking complex subunit 4, ENSG00000204815) is as follows. Component of the outer dynein arm-docking complex (ODA-DC) that mediates outer dynein arms (ODA) binding onto the doublet microtubule. Plays an essential role for the assembly of ODA-DC and for the docking of ODA in ciliary axoneme. .
