"Retinoic acid is considered as the earliest factor for regulating anteroposterior axis of neural tube and positioning of structures in developing brain through retinoic acid response elements (RARE) consensus sequence (5′–AGGTCA–3′) in promoter regions of retinoic acid-dependent genes."[1]

"Several studies have suggested that the target gene of the RA signal generally contains two direct-repeat half sites of the consensus sequence AGGTCA that are spaced by one to five base pairs (14,16,32,38)."[2]

"Xavier-Neto’s review demonstrated that the magic AGGTCA has high affinity but poor specificity (16). Some other [nuclear receptors] NRs also utilized the RARE with the same spacer models that are used by RXRs/RARs, for example, orphan receptors, vitamin D receptors (VDR) and peroxisome proliferator-activated receptors (PPAR) (32,39). Identifying a bona fide RARE is more difficult than a simple inspection. In order to attribute the RARE in Cx43 to a candidate sequence, some observations have been conducted in our study using molecular, biological and biophysical methods and functional approaches. In a ligand-dependent luciferase assay, RARE was located between the −1,426 to −341 base pair position. The constitutively active mutant Cx43 RARE represses the luciferase activity in the absence of the ligand and has no response to the 9cRA. Our findings indicate that RARE in the Cx43 promoter is a functional element."[2]

Human genes

Additional response elements that include the 5'-AGGTCA-3' are Q elements, ROR-response elements and Thyroid hormone response elements.

Consensus sequences

A likely general consensus sequence may be 5'-AG(A/G)TCA-3'.[2]

Samplings

Copying the apparent consensus sequence for the RARE (AGGTCA) and putting it in "⌘F" finds two located between ZSCAN22 and A1BG and three between ZNF497 and A1BG as can be found by the computer programs.
