Intracellular signal transduction pathways require a high degree of spatial and temporal resolution in order to deliver the appropriate outputs. Specific signaling mediated by the ubiquitous second messenger cAMP and its effector, the cAMP-dependent protein kinase (PKA), is governed by the spatial organization of different pathway components by A-kinase anchoring proteins (AKAPs). This review discusses the history and future of anchored cAMP signaling pathways.
细胞内信号转导通路需要高度的空间和时间分辨率,以便产生适当的输出。由普遍存在的第二信使环磷酸腺苷(cAMP)及其效应物——cAMP依赖性蛋白激酶(PKA)介导的特定信号传导,受A激酶锚定蛋白(AKAPs)对不同通路组分的空间组织调控。本文综述了锚定cAMP信号通路的历史与未来。
