MORC3 (MORC Family CW-Type Zinc Finger 3) is a member of the evolutionarily conserved MORC protein family, implicated in chromatin remodeling, transcriptional regulation, and DNA damage response. It contains an N-terminal GHKL ATPase domain and a C-terminal CW-type zinc finger domain, which mediate ATP-dependent chromatin interactions and recruitment of epigenetic modifiers. MORC3 is primarily localized in the nucleus and plays roles in innate immune signaling, epigenetic silencing, and genome stability maintenance.
Recombinant MORC3 protein is engineered for functional studies, typically expressed in bacterial (e.g., E. coli) or mammalian systems with affinity tags (His, GST) for purification. Its production enables biochemical characterization, including ATPase activity assays, chromatin-binding studies, and interaction mapping with partners like HSP90 or histone-modifying enzymes. Structural studies using recombinant MORC3 have revealed autoinhibitory conformations regulated by post-translational modifications.
Dysregulation of MORC3 is linked to autoimmune diseases (e.g., Sjögren's syndrome), cancers, and viral defense mechanisms. It interacts with the HUSH complex to repress retrotransposons and participates in antiviral responses by modulating interferon-stimulated genes. Pathogenic mutations (e.g., p.E30K) impair its chromatin remodeling activity, contributing to disease pathogenesis. Current research utilizes recombinant MORC3 to dissect its role in chromatin compaction, DNA repair pathways, and crosstalk with immune signaling cascades, offering therapeutic insights for related disorders.
