CNBP (CCHC-type zinc finger nucleic acid binding protein) is a conserved single-stranded nucleic acid binding protein that functions as both a transcriptional and translational regulator 1. The protein acts as a nucleic acid chaperone, remodeling G-rich secondary structures in DNA and RNA to regulate gene expression 2. CNBP participates in multiple cellular processes including ribosome biogenesis, cell proliferation control, and neural development 31. In disease contexts, expansions of CCTG repeats in the CNBP gene cause myotonic dystrophy type 2 (DM2), a multisystem disorder affecting skeletal muscle, heart, and brain 45. Reduced CNBP levels in DM2 contribute to brain atrophy and neuromotor defects 5. Beyond DM2, CNBP has broader clinical relevance: it restricts SARS-CoV-2 replication during infection 6, and elevated CNBP expression drives neuroblastoma progression through phase separation-mediated modulation of ribosome biogenesis 3. CNBP also participates in monocyte trained immunity following myocardial infarction, contributing to accelerated atherosclerosis 7. Post-translational modifications regulate CNBP localization and activity, with AMPK-dependent phosphorylation affecting protein stability 5. The protein's diverse roles suggest it integrates multiple cellular signaling pathways.
