Abstract excerpt
Members of the sterol regulatory element-binding protein (SREBP) family of transcription factors control cholesterol and lipid metabolism and play critical roles during adipocyte differentiation. The transcription factor SREBP1 is degraded by the ubiquitin-proteasome system following phosphorylation of Thr426 and Ser430 in its phosphodegron. We now demonstrate that the glycogen synthase kinase...
