General annotation (Comments)

Function

Has an ATP-independent isopeptidase activity, cleaving at the C-terminus of the ubiquitin moiety. In vitro, isoform 2, but not isoform 3, shows deubiquitinating activity.

Catalytic activity

Ubiquitin C-terminal thioester + H2O = ubiquitin + a thiol.

Tissue specificity

Testis specific. Expressed in various cancer cell lines. Ref.1 Ref.2

Involvement in disease

Involved in tumorigenesis.

Miscellaneous

The USP6 gene only exists in the primate lineage.

Sequence similarities

Belongs to the peptidase C19 family.

Contains 1 Rab-GAP TBC domain.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P35125-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: P35125-2)

Also known as: 213(ORF2);

The sequence of this isoform differs from the canonical sequence as follows:
     1-317: Missing.
     318-359: GLWARLRNQF...TRKQGDLPPP → MPQRLPHARQ...HRDPKDSRDA
Isoform 3 (identifier: P35125-3)

Also known as: 210(ORF1); oncTre210p;

The sequence of this isoform differs from the canonical sequence as follows:
     774-786: NFPQDNQKVQLSV → ISPLHHLQMECSP
     787-1406: Missing.
Note: Was shown to be tumorigenic in transfected mice and seems not to act as GTPase activating protein.
