Sentrin/SUMO-specific proteases (SENPs) reversibly regulate the covalent modification of proteins by SUMO. SENP3 and 5 share considerable sequence homology and exhibit similar substrate specificity, as they are active against SUMO-2 and SUMO-3 but less so for SUMO-1. They are more closely related than to SENP1/2. This entry covers the N-terminal domain of SENP5, which contains a conserved region directly preceding the catalytic domain, which is shared with SENP3. This domain is responsible for the subcellular localisation [1]. SENP3 and 5 colocalise in the nucleolus and their depletion causes defects in ribosome biogenesis [2].
