| + | [[http://www.uniprot.org/uniprot/VDR_RAT VDR_RAT]] Nuclear hormone receptor. Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Regulates transcription of hormone sensitive genes via its association with the WINAC complex, a chromatin-remodeling complex. Recruited to promoters via its interaction with the WINAC complex subunit BAZ1B/WSTF, which mediates the interaction with acetylated histones, an essential step for VDR-promoter association. Plays a central role in calcium homeostasis.<ref>PMID:17227670</ref> [[http://www.uniprot.org/uniprot/MED1_HUMAN MED1_HUMAN]] Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors.<ref>PMID:9653119</ref> <ref>PMID:10406464</ref> <ref>PMID:12218053</ref> <ref>PMID:12037571</ref> <ref>PMID:11867769</ref> <ref>PMID:12556447</ref> <ref>PMID:14636573</ref> <ref>PMID:15471764</ref> <ref>PMID:15340084</ref> <ref>PMID:15989967</ref> <ref>PMID:16574658</ref> | ||

| + | Fluorescent molecules have contributed to basic biological research but there are currently only a limited number of probes available for the detection of non-enzymatic proteins. Here, we report turn-on fluorescent probes mediated by conjugate addition and cyclization (TCC probes). These probes react with multiple amino acids and exhibit a 36-fold greater emission intensity after reaction. We analyzed the reactions between TCC probes and nuclear receptors by electrospray ionization mass spectrometry, X-ray crystallography, spectrofluorometry, and fluorescence microscopy. In vitro analysis showed that probes consisting of a protein ligand and TCC could label vitamin D receptor and peroxisome proliferator-activated receptor gamma. Moreover, we demonstrated that not only a ligand unit but also a peptide unit can label the target protein in a complex mixture. | ||
