Competency of IN to form multimeric assemblies is functionally critical, presenting an approach for anti-HIV strategies. Multimerization of IN depends on interactions between the distinct subunit domains and amongst the flanking protomers. Here we elucidate an overlooked docking cleft of IN core domain that anchors the Nterminal helix-turn-helix (HTH)-motif in a highly preserved and functionally critical configuration. Crystallographic structure of IN core domain in complex with Fab specifically targeting this cleft reveals a steric overlap that would inhibit HTH-docking, C-terminal domain contacts, DNA binding and subsequent multimerization. While Fab inhibits in vitro IN integration activity, in vivo it abolishes virus particle production by specifically associating with preprocessedIN within Gag-Pol and interfering with early cytosolic Gag/Gag-Pol assemblies. The HTHdocking cleft may offer a fresh hotspot for future anti-HIV intervention strategies.Publication Metadata only Characterization of engineered actin binding proteins that control filament assembly and structure.(2010-11-12T00:00:00Z) Brawley, CM; Uysal, SERDAR; Kossiakoff, AA; Rock, RS; UYSAL, SERDARPublication Metadata only Generating conformation-specific synthetic antibodies to trap proteins in selected functional states.(2013-03-15T00:00:00Z) Paduch, M; Koide, A; Uysal, SERDAR; Rizk, SS; Koide, S; Kossiakoff, AA; UYSAL, SERDAR
