Predicted to enable death receptor binding activity and ubiquitin ligase-substrate adaptor activity. Predicted to be involved in regulation of signal transduction; regulation of ubiquitin-protein transferase activity; and ubiquitin-dependent protein catabolic process via the C-end degron rule pathway. Predicted to act upstream of or within branching involved in prostate gland morphogenesis; epithelial cell maturation involved in prostate gland development; and protein ubiquitination. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of Cul2-RING ubiquitin ligase complex. Predicted to be active in cytoplasm and nucleus. Orthologous to human FEM1B (fem-1 homolog B). [provided by Alliance of Genome Resources, Apr 2022]
