MRGBP (Morf-Related Gene on Chromosome 15 Binding Protein), also known as MRG15-binding protein or MRGBP, is a conserved eukaryotic protein involved in chromatin remodeling and epigenetic regulation. It was initially identified as a component of the NuA4/TIP60 histone acetyltransferase (HAT) complex, which plays a critical role in DNA repair, transcription regulation, and cell cycle control. MRGBP functions as a scaffold or adaptor protein, mediating interactions between chromatin-modifying complexes and specific histone marks. Structurally, it contains a chromodomain-like region that may recognize methylated histone residues (e.g., H3K36me) and a C-terminal domain for binding partner proteins like MRG15.
Studies reveal MRGBP’s involvement in multiple pathways. It participates in the acetylation of histones H4 and H2A, facilitating chromatin relaxation during DNA damage repair. Additionally, MRGBP interacts with the Sin3A/HDAC complex, linking histone acetylation and deacetylation processes. Its role extends to embryonic development, stem cell maintenance, and cellular senescence. Dysregulation of MRGBP is associated with cancer progression, as altered expression impacts genomic stability and oncogene expression.
Recombinant MRGBP proteins are typically produced in bacterial or mammalian expression systems for biochemical assays, structural studies, and drug discovery. These tools enable exploration of its molecular interactions, post-translational modifications, and therapeutic targeting potential in diseases linked to epigenetic dysfunction. Research on MRGBP continues to uncover its multifaceted roles in bridging chromatin dynamics with cellular homeostasis.
