phospho-CYLD(Ser418) 磷酸化微管结合蛋

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

【求助】P53的翻译后修饰都有哪些？ 怎样验证其修饰后与靶标启动子的结合活性的变化？

，如Ser313、Ser314、Thr377、Ser378(被CHK1 ,CHK2磷酸化)、Ser366 (只被CHK2磷酸化)、Thr387 (只被CHK1磷酸化)。这些位点的磷酸化可能会改变 Lys373、Lys382乙酰化的方式，但不会改变Lys320，因此可以用来区分P300/CREB结合蛋白（CBP）和P300/CBP 相关因子(PCAF)活性[20].。 当大多数p53的磷酸化可以增强蛋白质的稳定性和活性时，一些位点的磷酸化（Thr55 、Thr155 、Ser205

), and causes activation of KOR. Agonist-activated KOR becomes a substrate for G protein receptor kinase (GRK), which phosphorylates the Ser369 residue at the C-terminal tail of the receptor in the first step in the β-Arrestin-dependent desensitization cascade
