SREBP-2
Transcriptional activator required for lipid homeostasis. Regulates transcription of the LDL receptor gene as well as the cholesterol and to a lesser degree the fatty acid synthesis pathway. Binds the sterol regulatory element 1 (SRE-1) (5'-ATCACCCCAC-3') found in the flanking region of the LDRL and HMG-CoA synthase genes. Belongs to the SREBP family. Ubiquitously expressed in adult and fetal tissues. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
