背景 | The stress-activated protein kinase/Jun-amino-terminal kinase SAPK/JNK is potently and preferentially activated by a variety of environmental stresses including UV and gamma radiation, ceramides, inflammatory cytokines, and in some instances, by growth factors and GPCR agonists (1-6). As with the other MAPKs, the core signaling unit is composed of a MAPKKK, typically MEKK1-MEKK4, or by one of the mixed lineage kinases (MLKs), which phosphorylate and activate MKK4/7. Upon activation, MKKs phosphorylate and activate the SAPK/JNK kinase (2). Stress signals are delivered to this cascade by small GTPases of the Rho family (Rac, Rho, cdc42) (3). Both Rac1 and cdc42 mediate the stimulation of MEKKs and MLKs (3). Alternatively, MKK4/7 can be activated in a GTPase-independent mechanism via stimulation of a germinal center kinase (GCK) family member (4). There are three SAPK/JNK genes each of which undergoes alternative splicing resulting in numerous isoforms (3). SAPK/JNK, when active as a dimer, can translocate to the nucleus and regulate transcription through its effects on c-Jun, ATF-2, and other transcription factors (3,5). |

Relationship between protein concentration of lysates from untreated and UV-treated 293 cells and immediate light generation with chemiluminescent substrate is shown. Cells (70-90% confluence) were treated with or without UV and lysed after incubation at 37ºC for 30 minutes. The graph inset corresponding to the shaded area shows high sensitivity and a linear response at the low protein concentration range.图中显示了未经处理和紫外照射的293细胞溶解产物蛋白质浓度之间的关系,以及用化学发光底物产生的即使光束。293细胞(70-90%细胞生长汇合)紫外照射和未经处理,37ºC 恢复30min后裂解。图片中的阴影区域表示高度敏感性和低浓度时的线性响应 。 |
