产品介绍 : PRPK is a 253 amino acid protein kinase that phosphorylates Ser15 of p53. PRPK phosphorylation of p53 causes increased stabilization and activity of p53. CGI-121 may act as an inhibitor of the PRPK-p53 interaction, thus preventing the phosphorylation of p53. Unphosphorylated p53 is degraded by the ubiquitin-proteasome pathway, which may ultimately lead to cell proliferation. PRPK contains a protein kinase domain with a conserved catalytic core. PRPK is localized to the nucleus of the cell and is highly expressed in testis, with lower expression in heart, kidney and spleen.
Function:
Component of the EKC/KEOPS complex that is required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t6A37) in tRNAs that read codons beginning with adenine. The complex is probably involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37. TP53RK has ATPase activity in the context of the EKC/KEOPS complex and likely plays a supporting role to the catalytic subunit OSGEP (By similarity). Atypical protein kinase that phosphorylates 'Ser-15' of p53/TP53 protein and may therefore participate in its activation.
Subcellular Location:
Nucleus.
Tissue Specificity:
Highly expressed in testis. Weakly expressed in heart kidney and spleen.
Similarity:
Belongs to the protein kinase superfamily.
Contains 1 protein kinase domain.

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
佚名 (一)抗体的反馈调节作用 抗体对免疫应答也有反馈调节作用。抗体是免疫应答的产物,抗体产生之后又可抑制其后的抗体产生。将抗体注入非免疫的机体,可阻止其后注入抗原引起的免疫应答,这一现象在临床上应用成功地预防了新生儿溶血性疾病的发生。该疾病是因母子间RH血型不符引起的。应用抗Rh因子抗体给分娩Rh+胎儿的Rh-产妇注射,由于分娩过程中进入母体Rh
