  • DUBA4
  • KIAA0459
  • OTU domain containing 3
  • OTUD3


OTU domain-containing protein 3 (OTUD3) is a specialized cysteine protease and a member of the ovarian tumor (OTU) protein super-family with a predicted molecular weight of 45 kDa. The human protein shares 83% amino acid sequence identity with its mouse ortholog. OTUD3 is exceedingly well characterized in terms of the structure-function relationship that results in the enzymes preferred polyubiquitin substrates. This untagged recombinant protein contains the catalytic (OTU) and UBA-like (Ubiquitin Associated) domains of OTUD3, and demonstrates a strong preference for K6- and K11-linked polyubiquitin chains.
