Supplementary information

PTBP1 also known as polypyrimidine tract-binding protein 1 or hnRNP I is a protein involved in RNA binding. It weighs approximately 57 kDa and is known for its expression in diverse cell types especially in the nucleus of eukaryotic cells. PTBP1 contains four RNA recognition motifs which allow it to interact with polypyrimidine-rich sequences in pre-mRNA. This interaction plays an important role in RNA splicing and the regulation of alternative splicing events.
Biological function summary

PTBP1 influences the stability transport and translation of mRNA molecules. It is part of the heterogeneous nuclear ribonucleoprotein complex which plays a fundamental role in the processing and modification of pre-mRNA into mature mRNA. This activity impacts the expression of a wide range of genes affecting cellular function and growth. PTBP1 regulates mRNA metabolism contributing significantly to post-transcriptional gene regulation.

Pathways

The involvement of PTBP1 spans the management of alternative splicing and the modulation of gene expression. It participates importantly in the alternative splicing pathway alongside proteins like PTBP2 which perform overlapping functions in neurons. PTBP1 affects exon inclusion or exclusion influencing the genetic diversity presented in protein forms within cells. It also plays a role in the exon junction complex pathway impacting post-translational modifications and protein interactions.

Variations in PTBP1 function are linked to conditions such as cancer and neurological disorders. Altered expression levels or mutations can contribute to carcinogenesis through the misregulation of splice variants specific to oncogenes and tumor suppressor genes. In neurological disorders PTBP1 interacts with proteins like FUS affecting the regulation of neuronal-specific alternative splicing. Misbalance in these interactions can have significant pathological implications contributing to diseases such as amyotrophic lateral sclerosis (ALS) and glioblastomas.

Target data

Plays a role in pre-mRNA splicing and in the regulation of alternative splicing events. Activates exon skipping of its own pre-mRNA during muscle cell differentiation. Binds to the polypyrimidine tract of introns. May promote RNA looping when bound to two separate polypyrimidine tracts in the same pre-mRNA. May promote the binding of U2 snRNP to pre-mRNA. Cooperates with RAVER1 to modulate switching between mutually exclusive exons during maturation of the TPM1 pre-mRNA. Represses the splicing of MAPT/Tau exon 10 (PubMed : 15009664). Binds to polypyrimidine-rich controlling element (PCE) of CFTR and promotes exon skipping of CFTR exon 9, thereby antagonizing TIA1 and its role in exon inclusion of CFTR exon 9 (PubMed : 14966131). Plays a role in the splicing of pyruvate kinase PKM by binding repressively to a polypyrimidine tract flanking PKM exon 9, inhibiting exon 9 inclusion and resulting in exon 10 inclusion and production of the PKM M2 isoform (PubMed : 20010808). In case of infection by picornaviruses, binds to the viral internal ribosome entry site (IRES) and stimulates the IRES-mediated translation (PubMed : 21518806).
