Component of the outer dynein arm-docking complex (ODA-DC) that mediates outer dynein arms (ODA) binding onto the doublet microtubule (PubMed:27486780). Involved in mediating assembly of both ODAs and their axonemal docking complex onto ciliary microtubules (PubMed:23849778). Component of the outer dynein arm-docking complex along with ODAD1, ODAD3, and ODAD4. Expressed in respiratory epithelial cells (at protein level). The disease is caused by variants affecting the gene represented in this entry. Contrary to the wild-type protein, disease-causing variant Trp-927 is unable to rescue the phenotype (randomization of heart looping) of the morpholino knockdown of the orthologous protein in zebrafish (PubMed:23849778).
