Ubiquitin Specific Peptidase 8 (USP8)

Ubiquitin, a highly conserved protein involved in the regulation of intracellular protein breakdown, cell cycle regulation, and stress response, is released from degraded proteins by disassembly of the polyubiquitin chains.

During analysis of randomly sampled human coding sequences from the myeloid cell line KG-1, Nomura et al. (1994) identified a novel cDNA, which they referred to as KIAA0055, that was related to the tre2 oncogene. Janssen et al. (1998) found that HUMORF8 encodes a putative deubiquitinating enzyme. Janssen et al. (1998) analyzed DNA from a patient with chronic myeloproliferative disorder. They identified an oncogenic fusion of the 5-prime end of p85-beta with the 3-prime end of HUMORF8.
