Enables identical protein binding activity and ubiquitin-ubiquitin ligase activity. Involved in several processes, including DNA damage checkpoint signaling, cellular protein metabolic process, and mRNA splicing, via spliceosome. Acts upstream of or within protein polyubiquitination. Located in cytoplasm, nuclear speck, and site of double-strand break. Part of Prp19 complex and U2-type catalytic step 2 spliceosome. Colocalizes with DNA replication factor A complex. Synonyma: PSO4, SNEV, PRP19, UBOX4, hPSO4, NMP200
