PTBP1 (Polypyrimidine Tract Binding Protein 1) is a gene that encodes a protein involved in RNA processing and splicing. This gene is implicated in neurodegenerative diseases and represents a potential therapeutic target.
PTBP1 encodes a nuclear RNA-binding protein that regulates alternative splicing and RNA processing. It binds to polypyrimidine-rich sequences in pre-mRNAs and influences the inclusion or exclusion of exons. PTBP1 is involved in neuronal development, GABA receptor splicing, and stress response. In neurodegeneration, PTBP1 misregulation contributes to aberrant splicing patterns and RNA toxicity.
High expression in brain, particularly neurons. Also expressed in other tissues. Shown to be upregulated in certain neurodegenerative conditions.
