Predicted to enable cullin family protein binding activity; ubiquitin conjugating enzyme binding activity; and ubiquitin-like protein binding activity. Predicted to be involved in several processes, including protein neddylation; regulation of protein modification by small protein conjugation or removal; and response to UV-C. Predicted to be located in nucleus; perinuclear region of cytoplasm; and plasma membrane. Predicted to be part of ubiquitin ligase complex. Is expressed in genitourinary system. Orthologous to human DCUN1D3 (defective in cullin neddylation 1 domain containing 3). [provided by Alliance of Genome Resources, Apr 2022]
