From concept to application: Exploring the evolution and potential of DUBTAC technology

Deubiquitinase-targeting chimeras (DUBTAC), as a highly promising emerging technology, can precisely remove ubiquitin chains from target proteins by recruiting deubiquitinases (DUBs), thereby enhancing the stability of the target proteins. Multiple functional proteins, such as the tumor suppressor proteins p53, RB, PTEN, upon stabilization by DUBTAC, can effectively restore or enhance their physiological functions, thus achieving therapeutic effects. Currently, the DUBTAC technology is still in its early stage of development, yet it has broad application prospects and represents a technological approach for developing various "undruggable" targets. This article delves into the design strategy of DUBTAC, and screens and recommends some candidate proteins with the potential to serve as drug targets. We aim to provide perspective in drug design, structural optimization, target selection, and related aspects.
