Predicted to enable ubiquitin ligase-substrate adaptor activity. Predicted to be involved in protein polyubiquitination. Predicted to act upstream of or within several processes, including cerebrospinal fluid circulation; determination of left/right symmetry; and outer dynein arm assembly. Predicted to be located in cilium. Predicted to be part of SCF ubiquitin ligase complex. Orthologous to human DAW1 (dynein assembly factor with WD repeats 1).
