WebJan 30, 2014 · The splicing regulator Polypyrimidine Tract Binding Protein (PTBP1) has four RNA binding domains that each binds a short pyrimidine element, allowing recognition of diverse pyrimidine-rich sequences. This variation makes it difficult to evaluate PTBP1 binding to particular sites based on sequence al … WebPTB protein (polypyrimidine-tract-binding, also known as PTBP1/HNRNP I), functions as an alternative splice site repressor by binding preferentially to the polypyrimidine tract [19,24]. The role of PTB in alternative splicing sites has been previously connected with malignant transformation in cancer cells [25,26,27]. WebJan 31, 2024 · The mRNA and protein levels of PTBP1 had no change during decidualization (Figures 4A and 4B ), indicating that HOXA11-AS may attenuate decidualization by modulating PTBP1 function rather than its mRNA or protein expression.
