PTBP1

PTBP1,全稱為多聚嘧啶區結合蛋白1,常見別名有PTB、hnRNP I。作為一種關鍵的RNA結合蛋白,它能識別并結合RNA上的特定片段,調整基因轉錄產物的剪接模式,進而影響多種蛋白質的合成,參與細胞生長、分化等基礎生命活動。
在疾病領域,PTBP1異常表現與多種癌癥緊密相關——肺癌、乳腺癌中其表達升高會推動腫瘤細胞增殖和轉移;阿爾茨海默病等神經退行性疾病里,它的功能紊亂可能加劇神經元損傷。目前針對PTBP1的藥物研發處于早期探索階段,一些小分子抑制劑正在實驗室測試,試圖通過調控其活性干預疾病進程,但尚未有成熟藥物進入臨床應用。

CSB-RA987652A0HU

IHC image of CSB-RA987652A0HU diluted at 1:100 and staining in paraffin-embedded human breast cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
