The function of DNAAF11 (dynein axonemal assembly factor 11, Ensembl gene identifier ENSG00000129295) is as follows. Involved in dynein arm assembly, is important for expression and transporting outer dynein arm (ODA) proteins from the cytoplasm to the cilia (PubMed:23122589, PubMed:23527195, PubMed:33403504). Acts as a crucial component in the formation and motility of spermatozoal flagella (PubMed:33403504). {ECO:0000269|PubMed:23122589, ECO:0000269|PubMed:23527195, ECO:0000269|PubMed:33403504}.
