![]() | ![]() タイトル: CONTEXT-DEPENDENT VARIABILITY OF HIF HETERODIMERS INFLUENCES INTERACTIONS WITH MACROMOLECULAR AND SMALL MOLECULE PARTNERS. 著者: Joseph D Closson / Xingjian Xu / Meiling Zhang / Tarsisius T Tiyani / Leandro Pimentel Marcelino / Eta A Isiorho / Jason S Nagati / Joseph A Garcia / Kevin H Gardner / ![]() 要旨: Hypoxia inducible factors (HIFs) are transcription factors that coordinate cellular responses to low oxygen levels, functioning as an α/β heterodimer which binds a short hypoxia response element ...Hypoxia inducible factors (HIFs) are transcription factors that coordinate cellular responses to low oxygen levels, functioning as an α/β heterodimer which binds a short hypoxia response element (HRE) DNA sequence. Prior studies suggest HIF/HRE complexes are augmented by the binding of additional factors nearby, but those interactions are not well understood. Here, we integrated structural and biochemical approaches to investigate several functionally relevant HIF assemblies with other protein, small molecule, and DNA partners. First, we used cryo-electron microscopy (cryo-EM) to establish HIF-1 and HIF-2 form novel "dimer-of-heterodimers" (DoHD) complexes on extended human EPO enhancer sequences, showing that one heterodimer bound at a canonical HRE site with the second binding in an inverted fashion to an HRE-adjacent sequence (HAS) 8 bp away. Consistent with ARNT PAS-B domains predominating interactions within a DoHD, we found HIF-1 and HIF-2 assemble mixed DoHD complexes on the same DNA. Second, we saw substantial variability among ligands for isolated ARNT or HIF-2α PAS-B domains to bind larger complexes: for example, the ARNT PAS-B binding KG-548 and KG-279 ligands both bound the simpler HIF-2 heterodimer but exhibited differential binding to a HIF-2 DoHD. Finally, we combined cryo-EM and hydrogen-deuterium exchange by mass spectrometry (HDX-MS) to show how HIF-1 and HIF-2 heterodimers engage the transforming acidic coiled-coil containing protein 3 (TACC3) coactivator via both ARNT and HIF-α subunits, though this was unseen in the larger DoHD. Our findings highlight the importance of both molecular context and dynamics in biomolecular complex formation, adding to the complexities of potential regulation. | ||||||||||||
