背景介绍
MAP2K1 encodes MAPK1, also known as MEK1. MEK1 variants can enhance MEK1 expression and ERK1 phosphorylation that together lead to continuous activation of MEK/ERK signaling pathway. MEK1 bind directly to ERK2 through a region in the N terminus of MEK. In addition, a proline-rich (PR) regulatory sequence in MEK is also involved in MEK-ERK association and signal propagation. The coupling between MEK1 and ERK2 is enhanced through phosphorylation on S298 in the MEK1 PR region, whereas phosphorylation on MEK1 T292 releases the complex. MEK1 enzymatic activity is regulated by site-specific phosphorylation that can be activated with phosphorylation of Ser217/Ser221 by Raf kinase or suppressed by phosphorylation of Thr286 and Thr292 by CDK1 and CDK5 or Thr292 and Thr386 by ERK1/2.

文献和实验Using Phospho‐Motif Antibodies to Determine Kinase Substrates
the phosphorylation site; therefore, substrate?directed, phosphorylation?state?sensitive, motif?specific (?phospho?motif?) antibodies represent powerful tools to identify novel kinase substrates and to investigate mechanisms of substrate phosphorylation
1. 杂交瘤阳性克隆的筛选与克隆化 在HAT培养基中生长的杂交瘤细胞，只有少数是分泌预定特异性单克隆抗体的细胞，因此，必须进行筛选和克隆化。通常采用有限稀释法进行杂交瘤细胞的克隆化培养。采用灵敏、快速、特异的免疫学方法，筛选出能产生所需单克隆抗体的阳性杂交瘤细胞，并进行克隆扩增。经过全面鉴定其所分泌单克隆抗体的免疫球蛋白类型、亚类、特异性、亲和力、识别抗原的表位及其分子量后，及时进行冻存。2. 单克隆抗体的大量制备 单克隆抗体的大量制备重要采用动物体内诱生法和体外培养法。
液，加入6ml DMEM完全培养基，37℃孵育过夜，再换液。 7、培养过程中观察细胞生长情况。约2周后可观察到细胞病变（CPE）出现（如用pAdTrack-CMV质粒，由于含GFP,可观察到绿色荧光）。四、重组病毒鉴定 1、转导10-14d后，收集细胞沉淀，加入2ml灭菌的PBS混悬，冻融细胞，离心后收集上清保存于-80℃。 2、取30-50% 步骤1中上清，感染50-70%饱和度的25cm2方瓶中293细胞。2-3d后出现明显细胞病变。 3、感染后3-5d，当1/3-1/2细胞漂浮时
