Glycine-Rich Domain Competitive Inhibition

**Molecular Mechanism and Rationale** TAR DNA-binding protein 43 (TDP-43), encoded by the TARDBP gene, is a nuclear ribonucleoprotein that plays crucial roles in RNA metabolism, including transcriptional repression, pre-mRNA splicing, and mRNA stability regulation. The protein consists of two RNA recognition motifs (RRM1 and RRM2), a nuclear localization signal, and a C-terminal glycine-rich domain (GRD) spanning amino acids 274-414. Under pathological conditions, TDP-43 undergoes cytoplasmic m...
