Abstract: ULTImate YChemH is a chemical biology tool for direct targets identification. This method is based on the well-established yeast two-hybrid (Y2H) technology. The small molecule of interest is used as a bait to screen highly complex protein domain libraries. The small molecule - protein interactions are detected thanks to the reconstitution of an active transcription factor from DNA Binding Domain (DBD) and Activation Domain (AD) moieties. When an interaction takes place, the bait derivative bridges the gap between the DBD and the AD. This enables the expression of the reporter gene and subsequent yeast growth on a selective medium. Positive clones are then analyzed by sequencing to identify the protein partnersSummary: Identifying protein partners of a small bioactive molecule is of great
interest in many aspects of life sciences and specifically in the drug
discovery and development process cycle. It is a support to (i) decipher
the mechanism of action after for example a “High Content” screening,
(ii) study “off-target” effects, (iii) adjust therapeutic indications and
clinical regimens of a drug and (iv) consider drug repositioning.
