Sterol regulatory element-binding protein 2 (Q12772)

Uniprot ID Q12772
Protein Name Sterol regulatory element-binding protein 2
Gene Name SREBF2
Species Homo sapiens (Human)
Signal peptide(a) N Secretome P(b)
Function 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 (By similarity). Binds the sterol regulatory element 1 (SRE-1) (5'-ATCACCCCAC-3') found in the flanking region of the LDRL and HMG-CoA synthase genes. .

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
