|
Retinoid X receptor beta (RXR-beta or RXRB) is also known as NR2B2 (nuclear receptor subfamily 2, group B, member 2). GST-tagged Retinoid X receptor beta ligand-binding domain (RXRB-LBD) consists of a 218 a.a. GST tag (Schistosoma japonicum Glutathione S-Transferase, Acc# 1M99_A), a 15 a.a. flexible linker and a 245 a.a. RXRB-LBD, Acc# P28702.2, amino acids 289-533 aa (details). GST tagged RXRB-LBD was expressed in baculovirus-infected insect cells and purified using affinity chromatography (Fig. 1). RXRB-LBD was produced in the absence of detergents and exogenous ligands to ensure advanced performance in ligand-binding assays and coregulator displacement studies. |
