| 目标基因介绍 | Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. MAPK1/ERK2 and MAPK3/ERK1 are the 2 MAPKs which play an important role in the MAPK/ERK cascade. They participate also in a signaling cascade initiated by activated KIT and KITLG/SCF. Depending on the cellular context, the MAPK/ERK cascade mediates diverse biological functions such as cell growth, adhesion, survival and differentiation through the regulation of transcription, translation, cytoskeletal rearrangements. The MAPK/ERK cascade also plays a role in initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells by phosphorylating a number of transcription factors. About 160 substrates have already been discovered for ERKs. Many of these substrates are localized in the nucleus, and seem to participate in the regulation of transcription upon stimulation. However, other substrates are found in the cytosol as well as in other cellular organelles, and those are responsible for processes such as translation, mitosis and apoptosis. Moreover, the MAPK/ERK cascade is also involved in the regulation of the endosomal dynamics, including lysosome processing and endosome cycling through the perinuclear recycling compartment (PNRC); as well as in the fragmentation of the Golgi apparatus during mitosis. The substrates include transcription factors (such as ATF2, BCL6, ELK1, ERF, FOS, HSF4 or SPZ1), cytoskeletal elements (such as CANX, CTTN, GJA1, MAP2, MAPT, PXN, SORBS3 or STMN1), regulators of apoptosis (such as BAD, BTG2, CASP9, DAPK1, IER3, MCL1 or PPARG), regulators of translation (such as EIF4EBP1 and FXR1) and a variety of other signaling-related molecules (like ARHGEF2, DCC, FRS2 or GRB10). Protein kinases (such as RAF1, RPS6KA1/RSK1, RPS6KA3/RSK2, RPS6KA2/RSK3, RPS6KA6/RSK4, SYK, MKNK1/MNK1, MKNK2/MNK2, RPS6KA5/MSK1, RPS6KA4/MSK2, MAPKAPK3 or MAPKAPK5) and phosphatases (such as DUSP1, DUSP4, DUSP6 or DUSP16) are other substrates which enable the propagation the MAPK/ERK signal to additional cytosolic and nuclear targets, thereby extending the specificity of the cascade. Mediates phosphorylation of TPR in response to EGF stimulation. May play a role in the spindle assembly checkpoint. Phosphorylates PML and promotes its interaction with PIN1, leading to PML degradation. Phosphorylates CDK2AP2 (By similarity). Acts as a transcriptional repressor. Binds to a [GC]AAA[GC] consensus sequence. Repress the expression of interferon gamma-induced genes. Seems to bind to the promoter of CCL5, DMP1, IFIH1, IFITM1, IRF7, IRF9, LAMP3, OAS1, OAS2, OAS3 and STAT1. Transcriptional activity is independent of kinase activity. | ||

| 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。 | ||
