PTBP1 is a protein involved in RNA processing, splicing, and post-transcriptional regulation. This protein plays a role in neurodegenerative diseases and represents a potential therapeutic target.
PTBP1 contains four RNA recognition motifs (RRMs) that allow binding to polypyrimidine-rich sequences in target RNAs. The RRMs are arranged in a modular fashion, allowing flexible RNA binding. PTBP1 can shuttle between nucleus and cytoplasm, and its localization is regulated by post-translational modifications including phosphorylation and methylation.
PTBP1 is a multi-functional RNA-binding protein involved in:
In neurons, PTBP1 regulates splicing of ion channel transcripts, neurotransmitter receptor subunits, and neuronal development genes.
PTBP1 dysfunction contributes to neurodegeneration through multiple mechanisms:
