How does the RAS effector AFDN bind the polarity protein SCRIB? Our Biochemical Journal paper identifies a distinctive β-hairpin interaction using AlphaFold3 combined with biophysics. Surprisingly, disrupting SCRIB-binding prevents AFDN from complexing with activated KRAS. doi.org/10.1042/BCJ2...

A distinctive PDZ:β-hairpin interaction mediates AFDN complex with SCRIB and promotes binding to KRAS
PDZ domains canonically recognize short C-terminal peptide motifs, but numerous non-canonical binding mechanisms have also been described. We previously identified a direct interaction between the cel...
