Protein Kinase A (PKA) alpha and beta catalytic subunits are essential components in cellular signaling. PKA also known as cAMP-dependent protein kinase has its catalytic subunits encoded by PRKACA (alpha) and PRKACB (beta) genes. Alpha subunit has a mass of approximately 40-45 kDa. These proteins are expressed in various tissues including the brain heart and skeletal muscle. They play an important role in phosphorylating target proteins in response to increased cellular levels of cyclic adenosine monophosphate (cAMP).
Biological function summary
PKA alpha and beta catalytic subunits participate in many cellular processes. They are part of a larger complex with regulatory subunits that inhibit their activity. The complex remains inactive until cAMP binds to the regulatory subunits causing a conformational change that activates the catalytic subunits. Once activated PKA subunits phosphorylate various substrates to modulate functions such as metabolism transcription and memory.
Pathways
PKA catalytic subunits serve as key mediators in the cAMP signaling pathway. This pathway influences cellular responses to hormones like adrenaline and glucagon. As such PKA often interacts with proteins such as CREB (cAMP response element-binding protein) to regulate gene expression. PKA also has a role in the regulation of glycogen sugar and lipid metabolism working in concert with proteins like phosphorylase kinase.
Aberrant regulation of PKA catalytic subunits can lead to various conditions. Overactive or dysregulated PKA is associated with Cushing's syndrome often due to mutations in PRKACA. Additionally these catalytic subunits are implicated in certain cancers through alterations in the cAMP signaling pathway. The interaction between PKA and other proteins such as RII-beta (a regulatory subunit) is critical in understanding the molecular basis of these diseases.
