The coactivator LXXLL nuclear receptor recognition motif
1Lilly Research Laboratories, Eli Lilly and Company, Indianapolis, IN, USA.
Abstract:
Nuclear receptors require coactivator binding in order to activate transcription of their cognate target genes. Ligands regulate nuclear receptor (NR)-mediated recruitment of coactivators by binding to the ligand-binding domain of the receptor and inducing a conformational change allowing for recognition of a specific motif contained within the coactivator protein. This motif is known as the NR box or LXXLL (where L is leucine and X is any amino acid) domain. Here, we review the discovery of the domain as well as its characterization.
