Predicted to enable identical protein binding activity; nuclear localization sequence binding activity; and ubiquitin protein ligase activity. Predicted to be involved in negative regulation of signal transduction and protein ubiquitination. Predicted to act upstream of or within MAPK cascade and Ras protein signal transduction. Predicted to be located in cytosol; nuclear membrane; and nucleoplasm. Predicted to be part of ubiquitin ligase complex. Orthologous to human BRAP (BRCA1 associated protein).
