The directly repeated RG(G/T)TCA motifs of the rat and mouse cellular retinol-binding protein II genes are promiscuous binding sites for RAR, RXR, HNF-4, and ARP-1 homo- and heterodimers.

Abstract excerpt

We show here that the element which was previously characterized as a retinoid X receptor (RXR)-specific response element (RXRE) in the rat cellular retinol-binding protein II (CRBPII) gene is not conserved in the mouse gene. However, two conserved cis-acting elements (RE2 and RE3) located in the promoter region of the mouse and rat CRBPII genes mediate transactivation by retinoic acid receptors (RARs) and RXRs...
