General annotation (Comments)

Function	Deubiquitinating enzyme that specifically removes conjugated ubiquitin from CDC25A, thereby playing a key role in cell cycle regulation. Deubiquitination of CDC25A prevents its degradation by the proteasome during the G1/S and G2/M phases of the cell cycle and is required for cell-cycle progression. Has transforming capabilities on cell lines. May also function in cell apoptosis. Ref.1 Ref.5
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). Ref.1
Subcellular location	Nucleus By similarity.
Tissue specificity	Broadly expressed. Ref.1
Induction	Up-regulated by IL4/interleukin-4 and IL6/interleukin-6 (at protein level). Ref.1
Miscellaneous	Overexpressed in a subset of human breast cancers, overexpression leading to an abnormally high level of CDC25A, which arrests cells through replication stress or premature mitosis, the latter occurring when CDK1 is activated inappropriately (Ref.5).
Sequence similarities	Belongs to the peptidase C19 family. USP17 subfamily.
Caution	The RS447 megasatellite DNA is a highly polymorphic conserved tandem repetitive sequence which contains a copy of USP17. It is present with an interindividual variation in copy number and between 20 to 103 copies can be found in the genome both on chromosome 4 and chromosome 8.
