- _5 value "Activation is abolished when either CRE or SRE are removed/mutated. Furthermore, mutation of CRE abolishes SREBP-dependent activation after overexpression of SREBP-1a and CRE binding protein (CREB). This shows that CRE is essential, and that under ex vivo conditions CREB and SREBP cooperate in transactivating CYP51. Interestingly, protein kinase A shows a marked stimulation of the CYP51 promoter activity when overexpressed together with SREBP-1a but not when overexpressed with CREB, suggesting phosphorylation of SREBP-1a. Using a DNA probe containing all three regulatory elements, it is found that SREBP-1a, a CREB-like factor, and specificity protein (Sp1) all probably bind the CYP51 promoter. While SREBP-1a and the CRE-bound proteins are essential for the SREBP-dependent response, Sp1 apparently functions only to maximize sterol regulation of CYP51." provenance.
