MRG15 is a member of the mortality family of transcription factors that targets a wide variety of multiprotein complexes involved in transcription regulation, DNA repair, and alternative splicing to chromatin. The structure of the apo-MRG15 MRG domain implicated in interactions with diverse proteins has been described, but not in complex with any of its targets. Here, we structurally and functionally characterize the interaction between MRG15 and Pf1, two constitutively associated subunits of the histone deacetylase-associated Rpd3S/Sin3S corepressor complex. The MRG domain adopts a structure reminiscent of the apo state, whereas the Pf1 MRG-binding domain engages two discrete hydrophobic surfaces on the MRG domain via a bipartite motif comprising an alpha-helix and a segment in an extended conformation, both of which are critical for high-affinity interactions. Multiple MRG15 interactors share an FxLP motif in the extended segment, but equivalent sequence/helical motifs are not readily evident, implying potential diversity in MRG-recognition mechanisms. | MRG15 is a member of the mortality family of transcription factors that targets a wide variety of multiprotein complexes involved in transcription regulation, DNA repair, and alternative splicing to chromatin.
