Crystal Structure of the MRG15 MRG domain
Overview
The ubiquitous MRG/MORF family of proteins is involved in cell senescence, or the terminal loss of proliferative potential, a model for aging and tumor suppression at the cellular level. These proteins are defined by the approximately 20 kDa MRG domain that binds a plethora of transcriptional regulators and chromatin-remodeling factors, including the histone deacetylase transcriptional corepressor mSin3A and the novel nuclear protein PAM14, and they are also known components of the Tip60/NuA4 complex via interactions with the MRG binding protein (MRGBP). We present here the crystal structure of a prototypic MRG domain from human MRG15 whose core consists of two orthogonal helix hairpins. Despite the lack of sequence similarity, the core structure has surprisingly striking homology to a DNA-interacting domain of the tyrosine site-specific recombinases XerD, lambda integrase, and Cre. Site-directed mutagenesis studies based on the X-ray structure and bioinformatics identified key residues involved in the binding of PAM14 and MRGBP.
