蛋白质支架复合物是一种关键机制,通过这种机制,一个共同的信号通路可以发挥许多不同的功能。将信号酶隔离到特定的亚细胞环境中不仅可以确保酶靠近其相关靶标,还可以隔离这种活性以防止其他底物的不加选择的磷酸化。A激酶锚定蛋白(AKAP)是一个研究广泛的支架蛋白家族。这些锚定蛋白形成多蛋白复合物,其将cAMP信号传导与其他途径和信号传导事件整合。本文就AKAP功能的研究进展作一综述。
Protein scaffold complexes are a key mechanism by which a common signaling pathway can serve many different functions. Sequestering a signaling enzyme to a specific subcellular environment not only ensures that the enzyme is near its relevant targets, but also segregates this activity to prevent indiscriminate phosphorylation of other substrates. One family of diverse, well-studied scaffolding proteins are the A-kinase anchoring proteins (AKAPs). These anchoring proteins form multi-protein complexes that integrate cAMP signaling with other pathways and signaling events. In this review we focus on recent advances in the elucidation of AKAP function.
