  • PubMed Abstract: 
  • The extraterminal (ET) domain of BRD3 is conserved among BET proteins (BRD2, BRD3, BRD4), interacting with multiple host and viral protein-protein networks. Solution NMR structures of complexes formed between the BRD3 ET domain and either the 79-residue murine leukemia virus integrase (IN) C-terminal domain (IN 329-408 ) or its 22-residue IN tail peptide (IN 386-407 ) alone reveal similar intermolecular three-stranded β-sheet formations ...

    The extraterminal (ET) domain of BRD3 is conserved among BET proteins (BRD2, BRD3, BRD4), interacting with multiple host and viral protein-protein networks. Solution NMR structures of complexes formed between the BRD3 ET domain and either the 79-residue murine leukemia virus integrase (IN) C-terminal domain (IN 329-408 ) or its 22-residue IN tail peptide (IN 386-407 ) alone reveal similar intermolecular three-stranded β-sheet formations. 15 N relaxation studies reveal a 10-residue linker region (IN 379-388 ) tethering the SH3 domain (IN 329-378 ) to the ET-binding motif (IN 389-405 ):ET complex. This linker has restricted flexibility, affecting its potential range of orientations in the IN:nucleosome complex. The complex of the ET-binding peptide of the host NSD3 protein (NSD3 148-184 ) and the BRD3 ET domain includes a similar three-stranded β-sheet interaction, but the orientation of the β hairpin is flipped compared with the two IN:ET complexes. These studies expand our understanding of molecular recognition polymorphism in complexes of ET-binding motifs with viral and host proteins.
