Predicted to enable protein homodimerization activity; protein kinase binding activity; and ubiquitin protein ligase activity. Predicted to be involved in several processes, including positive regulation of I-kappaB kinase/NF-kappaB signaling; positive regulation of NF-kappaB transcription factor activity; and regulation of viral entry into host cell. Predicted to be active in cytosol and nucleoplasm. Is expressed in early conceptus and testis. Orthologous to human TRIML1 (tripartite motif family like 1).
