Predicted to enable ubiquitin ligase-substrate adaptor activity. Acts upstream of or within several processes, including cerebrospinal fluid circulation; determination of left/right symmetry; and outer dynein arm assembly. Predicted to be part of SCF ubiquitin ligase complex. Used to study Kartagener syndrome; primary ciliary dyskinesia; and visceral heterotaxy. Orthologous to human DAW1 (dynein assembly factor with WD repeats 1). [provided by Alliance of Genome Resources, Apr 2022]
