Phage Display Driven Identification and Computational Mapping of Macrocyclic Peptides Targeting RhoA G17V

Scientists identified a potential drug candidate against a previously untargetable cancer driver, opening possibilities for treating angioimmunoblastic lymphoma.

Phage display screening identified Z1, a macrocyclic peptide with 136 nM affinity for the neomorphic RhoA G17V oncogene driving angioimmunoblastic T-cell lymphoma—a target previously considered undruggable due to its rigid GTPase fold. This work establishes macrocyclic phage display as a generalizable platform for historically undruggable GTPases, though all current evidence is in vitro.
