The targeted protein degradation- proteolysis targeting chimeras (PROTAC) technology is an attractive strategy to evaluate the fast biology and changes in a target protein, and its degradation [1]. The PROTAC- a hetero bi functional small molecule, one end contains a ligand of protein of interest (POI) and other end E3 ligase ligand attached through a linker, there by formation of a ternary complex resulted in ubiquitination of E3 ligase and ultimately tagging target proteins (POI) that then are recognized by the proteasome for degradation [2]. PROTAC technology uses event driven process and catalytic mode of action, which is different than traditionally occupancy driven pathway and attracting from academia to industry.
