Structural and functional analyses show how the spliceosomal Prp3 protein concomitantly binds double- and single- stranded regions in U4/U6 di-snRNAs and serves to stabilize the U4/U6•U5 tri-snRNP for splicing.
The association of Rad52 with Rad51, while not critical for Rad51 filament formation, is crucial to protect Rad51 filaments from Srs2 translocase activity through the association of Rad52 with complete Rad51 filaments.
High affinity interactions with transport adaptors are important to shield the interaction surfaces of cytomatrix components to block fatal premature oligomerization of active zone proteins during axonal transport.
Novel capsaicin analogs with conserved chemistry but varying sizes were used as molecular rulers to investigate energetics of conformational changes in the ligand-binding pocket and mechanisms of TRPV1 ligand-gating.
The structure-based design established a new approach to control pathway-selective activation of opioid receptors, resulting in new dual MOR/KOR G-protein biased agonist analgesics with attenuated liabilities.
