Enables deubiquitinase activity; enzyme binding activity; and transcription coactivator activity. Contributes to histone H4 acetyltransferase activity. Involved in several processes, including G2/M transition of mitotic cell cycle; protein deubiquitination; and regulation of gene expression. Part of
This gene encodes a member of the peptidase protein family. The encoded protein functions as a deubiquitinase that is involved in upregulation of the pro-apoptotic Bim protein. This protein may act as a tumor suppressor by increasing levels of Bim to counteract anti-apoptotic signals in cancer cells
