Studied interactions of polypyrimidine tract-binding protein (PTBP1), pyruvate kinase M2 (PKM2), and STAT3 (signal transducer and activator of transcription 3 (show STAT3 Antibodies)) in oncogenesis of anaplastic large cell lymphoma (ALCL).

  3. Polypyrimidine tract binding protein (PTBP1) is a heterogeneous nuclear ribonucleoprotein (show PCBP2 Antibodies) (hnRNP (show HNRNPC Antibodies)) that plays roles in most stages of the life-cycle of pre-mRNA and mRNAs in the nucleus and cytoplasm.

  4. follow-up molecular analyses of one splicing factor (show SLU7 Antibodies) PTBP1 revealed its impact on disease-associated splicing patterns in Huntington's disease (HD). Collectively, our data provide genomic evidence for widespread splicing dysregulation in HD brains, and suggest the role of aberrant alternative splicing in the pathogenesis of HD

  5. CD5 (show CD5 Antibodies) transcription is increased, leading to the production of three mRNA isoforms by APA (show ENPEP Antibodies), all contributing for protein production, at different levels. PTBP1 binds in the vicinity of pA1 (show PAGR1 Antibodies), leading to an increase in mRNA levels and miR (show MLXIP Antibodies)-204 targets the longer CD5 (show CD5 Antibodies) mRNA.

  6. Increased expression of microRNA miR (show MLXIP Antibodies)-145 combined with knockdown of PTBP1 protein contributed to the greater and longer growth suppression compared with each single treatment.

  7. MiR-133b switched the PKM isoform expression from PKM2 to PKM1 through the silencing of PTBP1, which is an alternative splicer of PKM, leading to growth suppression through the induction of autophagy in part by the metabolic switching from glycolysis to oxidative phosphorylation for a short period of time.

  8. Results suggested that PTBP1 and PTBP1-associated miR-1 and -133b are crucial molecules for the maintenance of the Warburg effect in colorectal tumors.

  9. The polypyrimidine tract binding protein 1 (PTBP1) shields specific retroviral and cellular transcripts from nonsense-mediated mRNA decay.

  10. findings point to PKM2 and PTBP1 as new potential therapeutic targets to improve response of PDAC to chemotherapy

  4. This may account for the tight correlation between Hps1 with Ptbp1 expression levels observed across mammalian tissues.

  5. The expression levels of three splicing factors, ESRP1 (show ESRP1 Antibodies), PTB and SF2/ASF (show SRSF1 Antibodies), are significantly altered during cardiac hypertrophy in mice.

  6. Study reports that repression of a single RNA binding polypyrimidine-tract-binding (PTB) protein, which occurs during normal brain development via the action of miR (show MLXIP Antibodies)-124, is sufficient to induce trans-differentiation of fibroblasts into functional neurons.

  7. The polypyrimidine tract binding proteins PTBP1 and PTBP2 (show PTBP2 Antibodies) repressed Psd-95 (show DLG4 Antibodies) (also known as Dlg4 (show DLG4 Antibodies)) exon 18 splicing, leading to premature translation termination and nonsense-mediated mRNA decay.

  8. PTBP1 is not required for the earliest isovolumetric divisions and differentiation steps of the zygote up to the formation of the blastocyst.

  9. RBM4 (show RBM4 Antibodies) may synergize its effect on muscle cell-specific alternative splicing by down-regulating PTB expression and antagonizing the activity of PTB in exon selection

  10. splicing repressors hnRNP A1 and A2, as well as the polypyrimidine-tract-binding protein PTB, contribute to control of pyruvate kinase isoform M1 and M2 expression

  2. Two stretches of polypyrimidine tracts designated PPT1 and PPT2 which influence the IRES activity of cx55.5 protein were identified; deletion of PPT1 results in an appreciable decrease of the IRES activity

  1. PTB1 is a splicing factor (show SLU7 Antibodies) that influences alternative splicing and acts at the polypyrimidine tract.

  2. Alternative splicing (AS) patterns as well as the expression of key flowering regulators were massively changed in a PTB1/2 level-dependent manner.

  3. AtPTB1 and AtPTB2 are widely expressed in almost all tissues, with the highest expression levels in late-maturing and mature pollen grains, and are crucial for pollen germination. [AtPTB1]

PTBP1 Antigen Profile

Antigen Summary

This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA-binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene has four repeats of quasi-RNA recognition motif (RRM) domains that bind RNAs. This protein binds to the intronic polypyrimidine tracts that requires pre-mRNA splicing and acts via the protein degradation ubiquitin-proteasome pathway. It may also promote the binding of U2 snRNP to pre-mRNAs. This protein is localized in the nucleoplasm and it is also detected in the perinucleolar structure. Alternatively spliced transcript variants encoding different isoforms have been described.
