Predicted to enable cullin family protein binding activity; ubiquitin conjugating enzyme binding activity; and ubiquitin-like protein binding activity. Predicted to be involved in positive regulation of protein neddylation; positive regulation of ubiquitin-protein transferase activity; and protein neddylation. Predicted to be located in nucleus. Predicted to be part of ubiquitin ligase complex. Is expressed in early conceptus; genitourinary system; nervous system; and neural retina. Orthologous to human DCUN1D4 (defective in cullin neddylation 1 domain containing 4). [provided by Alliance of Genome Resources, Apr 2022]
