Predicted to enable ubiquitin protein ligase activity. Predicted to be involved in RNA splicing; isopeptide cross-linking via N6-glycyl-L-lysine; and negative regulation of chemokine-mediated signaling pathway. Predicted to be located in nucleoplasm. Predicted to be part of U2-type precatalytic spliceosome. Human ortholog(s) of this gene implicated in nonphotosensitive trichothiodystrophy 5. Orthologous to human RNF113A (ring finger protein 113A). [provided by Alliance of Genome Resources, Apr 2022]
