[Isoform 1]: Deubiquitinating enzyme that may play a role in the ubiquitin-dependent regulation of protein synthesis, downstream of mTORC1 . May associate with the protein synthesis initiation complex and modify its ubiquitination to repress translation . May also repress DNA synthesis and modify different cellular targets thereby regulating cell growth and proliferation . May also play a role in proteasome assembly and function . ; [Isoform 2]: Stimulates protein synthesis. Influences the expression of CCND1/cyclin D1 by promoting its translation and regulates MYC/c-Myc protein stability.
