Sterol regulatory element-binding protein 1 (SREBF1)

Transcriptional activator necessary for lipid homeostasis. Regulates transcription of the LDL receptor gene as well as the fatty acid and to a lesser degree the cholesterol synthesis pathway (By similarity).

Binds to the sterol regulatory element 1 (SRE-1) (5'-ATCACCCCAC-3'). Has dual sequence specificity binding to both an E-box theme (5'-ATCACGTGA-3') and to SRE-1 (5'-ATCACCCCAC-3').
