In this work, the authors develop mirror-image monobodies (Mb) made of D-amino acids against the BCR::ABL1 SH2 domain with high binding affinities. The heterochiral Mb-SH2 structures reveal an unusual binding mode. The D-Mbs are protease-resistant, inhibit BCR::ABL1 kinase activity and bind BCR::ABL1 in cell lysates.
