Protein Kinase A R2 (PKR2) also known as PRKAR2A is a regulatory subunit of Protein Kinase A (PKA). PKA is part of a larger complex known as the cAMP-dependent protein kinase which plays an important role in cellular signaling. PKA consists of regulatory and catalytic subunits with PKR2 serving as one of its regulatory forms. PKR2 possesses a molecular mass of approximately 47 kDa and is available in various human tissues with notable expression in the brain and cardiovascular system.
Biological function summary
PKR2 regulates the activity of PKA by binding to the catalytic subunit in the absence of cAMP therefore inhibiting its activity. When cAMP is present it binds to the regulatory subunit PKR2 leading to the release and activation of the catalytic subunit of PKA. PKR2 is an integral part of the PKA holoenzyme complex which plays a critical role in mediating cellular responses to hormonal stimulation.
Pathways
PKR2 is heavily involved in the cAMP-dependent signaling pathway. This pathway is essential for translating extracellular signals into cellular actions. It interacts with various effector proteins including adenylate cyclases and phosphodiesterases to modulate responses such as gene transcription metabolism and memory formation. PKR2-related activity influences pathways shared with proteins like the G-protein subunits which facilitate the effects of neurotransmitters.
PKR2 irregularities can impact conditions like heart failure and neurodegenerative diseases. Disrupted PKA pathway signaling involving PKR2 can contribute to cardiac dysfunction by affecting heart muscle contractility and hypertrophy. In neurodegenerative diseases the improper functioning of PKR2 can exacerbate disruptions in neural signaling. A connection exists between PKR2 and proteins such as CREB (cAMP response element-binding protein) which links PKR2's role to memory deficits observed in neurodegeneration.
