Predicted to enable ubiquitin-like ligase-substrate adaptor activity. Predicted to be involved in several processes, including protein polyubiquitination; proteolysis; and regulation of proteasomal protein catabolic process. Predicted to be part of SCF ubiquitin ligase complex. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in adenomatoid tumor; hepatocellular carcinoma; and peritoneal mesothelioma. Orthologous to human TRAF7 (TNF receptor associated factor 7).
