Ubiquitin specific protease 11 is an that in humans is encoded by the USP11.
USP11 belongs to the Ubiquitin specific proteases family (USPs) which is a sub-family of the Deubiquitinating enzymes (DUBs).
USPs are multiple domain proteases and belong to the C19 cysteine proteases sub‒family.
Protein ubiquitination controls many intracellular processes, including cell cycle progression, transcriptional activation, and signal transduction.
Ubiquitin conjugating enzymes and deubiquitinating enzymes, adds and removes ubiquitin.
Deubiquitinating enzymes are cysteine proteases that cleave ubiquitin from ubiquitin-conjugated protein substrates, and is encoded in a gene cluster on chromosome Xp11.23
