Protein attributes

Sequence length	644 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Protease that catalyzes two essential functions in the SUMO pathway: processing of full-length SUMO1, SUMO2 and SUMO3 to their mature forms and deconjugation of SUMO1, SUMO2 and SUMO3 from targeted proteins. Deconjugates SUMO1 from HIPK2. Deconjugates SUMO1 from HDAC1, which decreases its transcriptional repression activity. Ref.1 Ref.6 Ref.8 Ref.10
Subcellular location	Nucleus. Cytoplasm. Note: Shuttles between cytoplasm and nucleus. Ref.1 Ref.8 Ref.5
Tissue specificity	Highly expressed in testis. Expressed at lower levels in thymus, pancreas, spleen, liver, ovary and small intestine. Ref.7
Sequence similarities	Belongs to the peptidase C48 family.
