Predicted to enable JUN kinase binding activity and ubiquitin protein ligase activity. Predicted to be involved in positive regulation of stress-activated protein kinase signaling cascade; protein autoubiquitination; and ubiquitin-dependent protein catabolic process. Predicted to be located in several cellular components, including endoplasmic reticulum; late endosome membrane; and nucleoplasm. Predicted to be active in lysosomal membrane. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 73. Orthologous to human RNF13 (ring finger protein 13). [provided by Alliance of Genome Resources, Apr 2022]
