p53 is a nuclear protein which plays an essential role in the regulation of cell cycle specifically in the transition from G0 to G1. It is found in very low levels in normal cells however in a variety of transformed cell lines in high amounts and believed to contribute to transformation and malignancy. The open reading frame of p53 is 393 amino acids long, with the central region (consisting of amino acids from about 100 to 300) containing the DNA-binding domain. This proteolysis-resistant core is flanked by a C-terminal end mediating oligomerization and an N-terminal end containing a strong transcription activation signal. p53 binds as a tetramer to a PBS (p53-Binding Site) and activates the expression of downstream genes that inhibit growth and/or invasion. p53 binds as a tetramer to a p53-binding site (PBS) and to activate the expression of adjacent genes that inhibit growth and/or invasion. Deletion of one or both p53 alleles reduces the expression of tetramers, resulting in decreased expression of the growth inhibitory genes

文献和实验Science:直击肿瘤命门,Shibin Zhou 等开发靶向 TP53 突变的双特异性抗体
对突变型 p53 的药物被批准用于治疗含有这些突变的肿瘤患者。 2021 年 3 月 1 日,来自美国的 Bert Vogelstein, Sandra B. Gabelli 和 Shibin Zhou 团队研制出了一种靶向 TP53 突变基因的双特异性单链抗体(bispecific single-chain diabody,scDb)。这种双特异性抗体在体外和小鼠体内都能有效识别呈递新抗原的癌细胞,并激活 T 细胞,发挥抗肿瘤效应。 从理论上讲,这种双特异性抗体可以用来针对含有传统方法难以瞄准
免疫细胞可识别并杀伤有害的靶细胞(如突发性肿瘤细胞),是人体宿主防御机制的一个重要组成部分。抗体依赖性细胞介导的细胞毒性 (ADCC) 和 T 细胞杀伤是细胞介导的免疫应答的两种机制,其中的每个过程都涉及刺激免疫细胞亚群(例如,自然杀伤 (NK) 细胞或细胞毒性 T 淋巴细胞 (CTL)),使它们主动裂解靶细胞。 近期,约翰霍普金斯大学医学院的研究人员在Science期刊发表研究成果[1]。他们发现了靶向TP53突变的新抗原,筛选出一种抗体片段(H2-scFv)特异性识别灭活的肿瘤
dongreyuan 有的抗体名称上面写着Ab-33,比如,β-catenin(Ab-33)antibody,请问,Ab-33是什么意思? bettyzyj 这个抗体是非磷酸化的抗体non-phospho-antibody ,33 代表的是基因位点 dongreyuan 谢谢了 yhwangcams bettyzyj wrote
