SREBPs: metabolic integrators in physiology and metabolism

Recent advances have significantly increased our understanding of how sterol regulatory element binding proteins (SREBPs) are regulated at the transcriptional and post-transcriptional levels in response to cellular signaling. The phosphatidyl inositol-3-kinase (PI3K) and SREBP pathways intersect at multiple points, and recent insights demonstrate the importance of tight regulation of the PI3K pathway for regulating SREBPs in the adaptation to...
