Component of the outer dynein arm-docking complex (ODA-DC) that mediates outer dynein arms (ODA) binding onto the doublet microtubule. Involved in mediating assembly of both ODAs and their axonemal docking complex onto ciliary microtubules (By similarity). {ECO:0000250|UniProtKB:F1N2N9, ECO:0000269|PubMed:27486780, ECO:0000305|PubMed:23261302, ECO:0000305|PubMed:23261303}. This is the function of Ensembl gene identifier ENSG00000105479 (ODAD1, outer dynein arm docking complex subunit 1).
