Predicted to enable ubiquitin protein ligase binding activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process; protein polyubiquitination; and regulation of proteolysis. Predicted to be part of Cul3-RING ubiquitin ligase complex. Predicted to be active in cytoplasm and nucleus. Is expressed in early conceptus; oocyte; and secondary oocyte. Orthologous to human SPOP (speckle type BTB/POZ protein). [provided by Alliance of Genome Resources, Apr 2022]
