As a substrate of extracellular signal-related kinase (ERK), the p90 ribosome S6 kinase 1 (RSK1) is at the terminus of the Ras/ERK pathway. Residues 411-735 of human RSK1, covering the C-terminal serine/threonine kinase catalytic domain and the functionally important tail, were cloned into an Escherichia coli expression vector. The protein was expressed, purified and crystallized. The crystals diffracted to 2.7 A and belonged to space group P2(1), with unit-cell parameters a = 39.8, b = 143.8, c = 59.9 A, beta = 95.7 degrees.
作为细胞外信号调节激酶(ERK)的底物,p90核糖体S6激酶1(RSK1)位于Ras/ERK信号通路的末端。将人RSK1的411 - 735位残基(覆盖C末端丝氨酸/苏氨酸激酶催化结构域和功能重要的尾部)克隆到大肠杆菌表达载体中。该蛋白经表达、纯化和结晶。晶体衍射分辨率达到2.7 Å,属于P2(1)空间群,晶胞参数为a = 39.8、b = 143.8、c = 59.9 Å,β = 95.7°。
