Responsible for the altered behavior of the chimera. Suggests that the SLSR insertion in the ligand-binding domain of the RXR alpha/beta3 receptor is Physically with the retinoic acid receptor (RAR) to form heterodimers as detected by physicalĪssociation assays, and fails to bind DNA containing an RAR-responsive element. Moreover, the RXR alpha/beta3 protein fails to interact Receptors on retinoid-responsive promoters.

The RXRĪlpha/beta3 receptor exhibits dominant negative activity against active retinoid X and retinoic acid Co-transfectionĪssays reveal that a chimera RXR alpha/beta3 receptor fails to transactivate the RXR-specificĬRBPII promoter, whereas the identical chimera lacking the SLSR insertion is active.

Insertion on the transactivation and DNA-binding functions of the chimeric receptor. The corresponding domain from hRXR beta3, were used to investigate the consequences of the SLSR Chimeric receptors, in which the ligand-binding domain of hRXR alpha was substituted by Transcription polymerase chain reaction (RT-PCR) in all human tumor cell lines and mouse tissuesĮxamined. The isoform is generated by alternate use of a 3' splice acceptor site and is detectable by reverse Mammalian RXR - interactions during transcriptional activationĪn isoform of hRXR beta, termed hRXR beta3, contains an in-frame insertion of four amino acids (SLSR) in the ligand binding domain at codon 419.
