| 目标基因介绍 | Dual-specificity kinase which possesses both serine/threonine and tyrosine kinase activities (PubMed:21127067, PubMed:8769099, PubMed:30773093, PubMed:20981014, PubMed:23665168). Exhibits a substrate preference for proline at position P+1 and arginine at position P-3 (PubMed:23665168). Plays an important role in double-strand breaks (DSBs) repair following DNA damage (PubMed:31024071). Mechanistically, phosphorylates RNF169 and increases its ability to block accumulation of TP53BP1 at the DSB sites thereby promoting homologous recombination repair (HRR) (PubMed:30773093). Also acts as a positive regulator of transcription by acting as a CTD kinase that mediates phosphorylation of the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNAP II) POLR2A (PubMed:25620562, PubMed:29849146). May play a role in a signaling pathway regulating nuclear functions of cell proliferation (PubMed:14500717). Modulates alternative splicing by phosphorylating the splice factor SRSF6 (By similarity). Has pro-survival function and negatively regulates the apoptotic process (By similarity). Promotes cell survival upon genotoxic stress through phosphorylation of SIRT1 (By similarity). This in turn inhibits p53/TP53 activity and apoptosis (By similarity). Phosphorylates SEPTIN4, SEPTIN5 and SF3B1 at 'Thr-434' (By similarity). | ||

| 复苏 | 1)在37℃水浴中预热完全培养基。 2)将冻存管在 37℃水浴中解冻1-2分钟。 3)将冻存管转移到生物安全柜中,并用70%乙醇擦拭表面。 4)拧开冻存管管盖,将细胞悬液轻轻转移到含有9mL完全培养基的无菌离心管中。 5)在室温下以125g离心5-7分钟,弃上清。 6)用5mL的完整培养基重悬细胞沉淀,将细胞悬液转移到T25培养瓶中。 7)将细胞转移到37℃,5% CO2的培养箱中培养。 8)参考传代比例:1/2到1/3传代,2-5天长满。 | ||
| 传代 | 1)待培养瓶中细胞汇合度至80%-90%以上,可进行细胞传代。 2)将培养基、PBS、胰酶(0.25%Trypsin_EDTA Gibco 25200-056)等从4℃冰箱中拿出,置于37℃水浴中温度接近37℃时取出并在瓶子表面喷洒75%酒精后置于生物安全柜中。 3)从培养箱中取出待传代的培养瓶,瓶身喷洒75%酒精后置于生物安全柜中。 4)为避免冲散细胞,沿培养瓶上壁PBS润洗细胞,清洗细胞后弃去,T25加2mL。 5)加入对应体积的胰酶(T75加1.5mL,T25加0.5mL),并轻轻晃动瓶身使胰酶平铺满细胞底部。可根据实际情况适当增加或减少用量。约1-2min后大部分细胞脱落时,加入对应体积的完全培养基终止消化,并用5mL移液管轻轻吹打至细胞全部脱落。 6)将细胞悬液转移至15mL离心管,悬液300g离心5min,弃上清。 7)移取5mL完全培养基重悬细胞,按需求调整接种比例,并补充培养瓶中完全培养基,T75加至13-15mL,T25加至5mL,加1%双抗。 8)盖上瓶盖拧紧后轻轻晃动瓶身,使细胞混合均匀后置于37℃,5% CO4培养箱中。 | ||
| 细胞冻存 | 1)准备冻存液,并提前预冷。 2)确保待冻存的细胞满足冻存要求,用显微镜检查以下状态:健康的外观及形态特征、所处生长周期(对数晚期)、无污染或衰退迹象。 3)对细胞进行消化及离心处理(具体步骤参考传代培养流程) 4)按照每管1mL的量添加冻存液重悬细胞,吹打均匀后分装至冻存管。 5)将细胞放在程序降温盒中,在-80℃冰箱中冷冻。 6)后续将细胞转移到液氮罐中,以便长期储存。 | ||
