一般描述
蛋白激酶一种酶由两个亚单位（催化亚单位和调节亚单位）组成。催化亚基在环磷酸腺苷存在下作为单体存在，分子量为40,862 Da。
应用
牛心脏蛋白激酶A （PKA）催化亚单位已用于
- 研究PKA介导的IRK1（内向整流K+）通道抑制
- 体外 PKA磷酸化测定
- 体外亲和结合测定
- 研究PKA对功能活动运动神经元吸气驱动电流的影响
生化/生理作用
蛋白激酶A (PKA)控制Hedgehog信号转导，并参与增殖和命运决定。它可以使几种神经递质受体、转录因子和多种细胞内信号通路的成分磷酸化。
蛋白激酶A催化末端磷酸从ATP转移到存在于各种蛋白质上的苏氨酸或丝氨酸残基。这种蛋白质在没有环磷酸腺苷的情况下是无活性的，环磷酸腺苷是催化亚基和调节亚基结合在一起的地方。存在cAMP时，调节亚单位与cAMP结合并释放催化亚单位。
包装

Plasticity underlying adaptive, long-term changes in breathing behavior is hypothesized to be attributable to the modulation of respiratory motoneurons by intracellular second-messenger cascades. In quiescent preparations, protein kinases, including cAMP-dependent protein kinase A (PKA), potentiate glutamatergic inputs. However, the dynamic

Strongly rectifying IRK-type inwardly rectifying K+ channels are involved in the control of neuronal excitability in the mammalian brain. Whole-cell patch-clamp experiments show that cloned rat IRK1 (Kir 2.1) channels, when heterologously expressed in mammalian COS-7 cells, are inhibited following
