USP7-mediated deubiquitination and nuclear translocation of PFKM promotes brain tumor development by sensing fructose-2,6-bisphosphate. USP7 interacts with PFKM regulated by F-2,6-BP, resulting in the ubiquitination of PFKM K615 after GD treatment. Deubiquitinated PFKM translocates into nucleus and interacts with c-Myc. PFKM facilitates c-MYC binding to CPT1B promoter and promotes transcription of CPT1B, thereby enhancing FAO and cell survival.
