PKA Inhibitor Fragment (6-22) amide is primarily used in biochemical research to study protein kinase A (PKA) signaling pathways. It serves as a specific inhibitor, helping researchers understand the role of PKA in cellular processes such as metabolism, gene expression, and cell division. This peptide fragment is particularly valuable in experiments aimed at dissecting the mechanisms of PKA-mediated phosphorylation and its impact on various physiological functions. Additionally, it is utilized in drug discovery efforts to identify potential therapeutic agents targeting PKA-related diseases, including cancer, cardiovascular disorders, and neurological conditions. Its application extends to studying cAMP-dependent pathways, providing insights into cellular responses to hormonal and neurotransmitter signals.
