26657638 Data show that polypyrimidine tract-binding proteins nPTB and ROD1 interact with mitochondrial tRNA(Thr) in the cytoplasm outside of mitochondria.
26416554 PTBP1 and PTBP2 impaired autoregulation of SRSF3 in oral squamous cell carcinoma cancer cells.
25025966 MALAT1 binds to SFPQ releasing PTBP2 from the SFPQ/PTBP2 complex, the increased SFPQ-detached PTBP2 promotes cell proliferation and migration in colorectal cancer.
24286314 In T98G glioma cells, the level of sumoylated PTBP2 was reduced compared to that of normal brain cells. Overall, this study shows that PTBP2 is posttranslationally modified by SUMO1.
24264039 Defining the multifunctional roles of PTB will contribute to the understanding of key regulatory events in gene expression.
23174904 Changes in miR-223/PTBP2 pathway could contribute of abnormal splicing in chronic myeloid leukemia.
21282112 Regulation of the mutually exclusive exons 8a and 8 in the CaV1.2 calcium channel transcript by polypyrimidine tract-binding protein.
20379614 Clinical trial of gene-disease association and gene-environment interaction. (HuGE Navigator)
20160105 present fluorescence, NMR, and in vivo splicing data in support of a role of PTB in inducing RNA loops. We show that the RNA recognition motifs (RRMs) 3 and 4 of PTB can bind two distant pyrimidine tracts and bring their 5' and 3' ends in close proximity
17548433 Study shows that PTB can function as an anti-repressor molecule to counteract the splicing inhibitory activity of SRp30c.
16002244 The nPTB proximal promoter, although rich in G+C content and presenting putative binding sites for the transcription factors Sp1, NF-1, NF-kB and Oct-1, lacks a typical TATA box.
8626763 Polypyrimidine tract-binding protein (PTB) stimulates the binding of RNA Polymerase II and TRP-185 to HIV-1 TAR RNA, suggesting an interaction between PTB and HIV-1 Tat
