General annotation (Comments)
| Function | Deubiquitinase with an ATP-independent isopeptidase activity, cleaving at the C-terminus of the ubiquitin moiety. Catalyzes its own deubiquitination. In vitro, isoform 2, but not isoform 3, shows deubiquitinating activity. Promotes plasma membrane localization of ARF6 and selectively regulates ARF6-dependent endocytic protein trafficking. Is able to initiate tumorigenesis by inducing the production of matrix metalloproteinases following NF-kappa-B activation. Ref.7 Ref.8 Ref.9 |
| Catalytic activity | Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal). |
| Subunit structure | Interacts with RAC1 and CDC42. Interacts (via Rab-GAP TBC domain) with ARF6. Interacts with calmodulin (CALM1, CALM2 and/or CALM3); the interaction is calcium-dependent. Ref.5 Ref.7 Ref.8 |
| Subcellular location | Cell membrane. Cytoplasm. Endosome. Note: Localizes to the plasma membrane and to filamentous structures within the cell corresponding to ARF6 regulated tubular endosomes. Activation of RAC1 and CDC42 can direct the relocalization of USP6 to the plasma membrane in a manner that depends on the integrity of the actin cytoskeleton. Ref.5 Ref.7 |
| Tissue specificity | Testis specific. Expressed in various cancer cell lines. Ref.1 Ref.2 |
| Domain | The Rab-GAP TBC domain lacks GTPase activator activity but is necessary for interaction with ARF6. |
| Post-translational modification | Monubiquitinated; ubiquitination is calmodulin and calcium dependent. |
| Involvement in disease | Note=A chromosomal aberration involving USP6 is a common genetic feature of aneurysmal bone cyst, a benign osseous neoplasm. Translocation t(16;17)(q22;p13) with CDH11. The translocation generates a fusion gene in which the strong CDH11 promoter is fused to the entire USP6 coding sequence, resulting in USP6 transcriptional up-regulation. |
| 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. |
