- 靶标蛋白及功能: Serine/threonine-protein kinase involved in the control of the cell cycle; essential for meiosis, but dispensable for mitosis. Phosphorylates CTNNB1, USP37, p53/TP53, NPM1, CDK7, RB1, BRCA2, MYC, NPAT, EZH2. Triggers duplication of centrosomes and DNA. Acts at the G1-S transition to promote the E2F transcriptional program and the initiation of DNA synthesis, and modulates G2 progression; controls the timing of entry into mitosis/meiosis by controlling the subsequent activation of cyclin B/CDK1 by phosphorylation, and coordinates the activation of cyclin B/CDK1 at the centrosome and in the nucleus. Crucial role in orchestrating a fine balance between cellular proliferation, cell death, and DNA repair in human embryonic stem cells (hESCs). Activity of CDK2 is maximal during S phase and G2; activated by interaction with cyclin E during the early stages of DNA synthesis to permit G1-S transition, and subsequently activated by cyclin A2 (cyclin A1 in germ cells) during the late stages of DNA replication to drive the transition from S phase to mitosis, the G2 phase. EZH2 phosphorylation promotes H3K27me3 maintenance and epigenetic gene silencing. Phosphorylates CABLES1 (By similarity). Cyclin E/CDK2 prevents oxidative stress-mediated Ras-induced senescence by phosphorylating MYC. Involved in G1-S phase DNA damage checkpoint that prevents cells with damaged DNA from initiating mitosis; regulates homologous recombination-dependent repair by phosphorylating BRCA2, this phosphorylation is low in S phase when recombination is active, but increases as cells progress towards mitosis. In response to DNA damage, double-strand break repair by homologous recombination a reduction of CDK2-mediated BRCA2 phosphorylation. Phosphorylation of RB1 disturbs its interaction with E2F1. NPM1 phosphorylation by cyclin E/CDK2 promotes its dissociates from unduplicated centrosomes, thus initiating centrosome duplication. Cyclin E/CDK2-mediated phosphorylation of NPAT at G1-S transition and until prophase stimulates the NPAT-mediated activation of histone gene transcription during S phase. Required for vitamin D-mediated growth inhibition by being itself inactivated. Involved in the nitric oxide- (NO) mediated signaling in a nitrosylation/activation-dependent manner. USP37 is activated by phosphorylation and thus triggers G1-S transition. CTNNB1 phosphorylation regulates insulin internalization. Phosphorylates FOXP3 and negatively regulates its transcriptional activity and protein stability (By similarity). Phosphorylates CDK2AP2 (PubMed:12944431). Phosphorylates ERCC6 which is essential for its chromatin remodeling activity at DNA double-strand breaks (PubMed:29203878).
- 标签蛋白介绍: 粒曼生物定点Knock-in 体系能特异剪切人类第19 号染色体上的 AAVS1 位点,生成DNA 双链断裂(DSB),触发DNA 的自然修复机制,诱导位点与 AAVS1 供体 DNA 克隆之间发生同源重组(HR),将供体克隆上的 DNA 片段整合到基因组上的 safe harbor 位点。HiBiT小分子生物发光标签,分子大小1.3 kDa(11 个氨基酸残基)凭借 “尺寸极小、检测灵敏、无背景干扰” 的核心优势,成为蛋白表达追踪、互作分析、活细胞成像等研究的理想工具,尤其适合对标签干扰敏感的实验场景.
- 细胞背景: [HEK-293]细胞是剪切过的人腺病毒5(Ad5)转染的人胚肾细胞形成的永生化细胞,293 [HEK-293]细胞包含并表达转染的Ad5基因。早期报道中指出,293 [HEK-293]细胞基因组中含有腺病毒5(Ad5)基因组的左侧端和右侧端的DNA,但是现在明确了只存在其左侧端的DNA。经过对Ad5的插入点的克隆测序发现,Ad5的1-4344位线性核苷酸整合入293 [HEK-293]细胞19号染色体(19q13.2)。293 [HEK-293]细胞为人类腺病毒载体扩增的宿主,可表达异常的玻连蛋白的细胞表面受体,由整合素β1亚单位和玻连蛋白受体α-v亚单位组成。
