Background: SREBP1

SREBP1 (sterol regulatory element binding protein 1, also called SREBF1 or BHLHD1) is a bHLH-LZ (basic helix-loop-helix-leucine zipper) transcription factor that acts as a key lipogenic transcription factor controlled by glucose/insulin and preferentially regulates lipogenesis via activating genes involved in fatty acid as well as triglyceride synthesis. It is a transcriptional activator required for lipid homeostasis and regulates transcription of the LDL receptor gene as well as the fatty acid and to a lesser degree the cholesterol synthesis pathway. SREBP1 has a dual sequence specificity binding to both an E-box motif (5'-ATCACGTGA-3') and to SRE-1 (sterol regulatory element 1; 5'-ATCACCCCAC-3'). It exists as multi-pass membrane protein in the membranes of ER, Golgi apparatus and cytoplasmic vesicle /COPII-coated vesicles and moves from ER to Golgi in the absence of sterols. It forms a tight complex with SCAP in ER membranes and interacts with LMNA. AMPK phosphorylate SREBP1 leading to suppression of protein processing and nuclear translocation, and target gene expression repression. Moreover, SIK1 mediated phosphorylation at Ser-402 site represses its activity through inhibition of DNA-binding.
