Predicted to enable several functions, including RING-like zinc finger domain binding activity; ubiquitin protein ligase activity; and zinc ion binding activity. Predicted to contribute to ubiquitin-protein transferase activity. Involved in response to retinoic acid and spinal cord development. Predicted to be located in euchromatin; nuclear body; and sex chromatin. Predicted to be part of MLL1 complex and PRC1 complex. Biomarker of spina bifida. Orthologous to human RNF2 (ring finger protein 2). [provided by Alliance of Genome Resources, Apr 2022]
