ZUP1 and ovarian neoplasm: Cysteine proteases can be further divided into six families based on phylogenetic relationships’, namely ubiquitin-specific proteases (USPs), ovarian tumor proteases (OTUs), Machado−Josephin domain proteases (MJDs), ubiquitin C-terminal hydroxylases (UCHs), motif interacting with ubiquitin-containing novel DUB family proteases (MINDYs), and zinc finger-containing ubiquitin peptidase 1 (ZUP1).
