PKI (6-22) Amide, also known as PKA Inhibitor, functions as a specific inhibitor of Protein Kinase A (PKA), a pivotal enzyme in the regulation of diverse cellular processes through phosphorylation of target proteins. By selectively binding to the catalytic subunit of PKA, PKI (6-22) Amide effectively disrupts the enzyme′s activity, providing useful for researchers to elucidate the roles of PKA-mediated signaling pathways in cellular functions. Its utility is especially prominent in the study of cellular communication, gene expression, and the molecular mechanisms underlying various biological processes. By inhibiting PKA, PKI (6-22) Amide allows for the exploration of the enzyme′s contributions to these processes, making it an essential compound in the toolkit of molecular and cellular biology research. Its specificity and efficacy in modulating PKA activity without affecting other kinases make it an ideal candidate for dissecting the complex signaling networks governed by protein phosphorylation.
