The polypyrimidine tract occurs
Webb10 apr. 2024 · The structural integrity of the PNC is dependent upon its RNA and protein components and is mediated by the RNA-binding ribonucleoprotein, polypyrimidine tract binding (PTB) protein . Studies have shown that PNC is highly prevalent in cancers, particularly metastatic tumors, whether in transformed cell lines or the patient’s tumor … WebbUsing this approach, we found that the normally tight coupling between transcription and splicing is broken in situations where the intron's polypyrimidine tract is sequestered …

WebbIn this work, we compare different types of nitroxide-based and Gd ( III )-based spin labels attached to isolated RBDs of the polypyrimidine-tract binding protein 1 (PTBP1) and to short RNA fragments. In particular, we demonstrate experiments on spectroscopically orthogonal labelled RBD/RNA complexes.

WebbAbstract Splicing of exons 2 and 3 of a-tropomyosin (TM) involves mutually exclusive selection of either exon 3, which occurs in most cells, or of exon 2 in smooth muscle (SM) cells. The SM-specific selection of exon 2 results from the inhibition of exon 3. WebbThe polypyrimidine tract is a region of messenger RNA (mRNA) that promotes the assembly of the spliceosome, the protein complex specialized for carrying out RNA …
Webb1 nov. 1997 · The polypyrimidine tract of cdc 2-Int2 is critical for efficient splicing. Given the importance of the polypyrimidine tract for splicing in mammals, we wanted to assess whether sequences between the branch point and 3′ splice site might play a similar role in early intron recognition in S.pombe.
