What Does PKA Stand For?
PKA stands for Protein Kinase A
PKA, or Protein Kinase A, is a serine/threonine kinase that is activated by cyclic AMP (cAMP). It plays a crucial role in numerous cellular processes by phosphorylating various substrate proteins, thereby influencing signaling pathways related to metabolism, cell growth, and gene expression. PKA is essential for regulating physiological responses such as glycogen metabolism, muscle contraction, and the actions of hormones like adrenaline. Its dysregulation is associated with several diseases, making it a significant target for therapeutic interventions.
