Application

Protein Kinase A Inhibitor Fragment 6-22 amide has been used as a PKA inhibitor:
  • to study its effects on oocytes in two-electrode voltage clamp (TEVC) experiments
  • to study its effects on antinociception levels in mice
  • in PKA phosphorylation assay

Biochem/physiol Actions

Protein Kinase A Inhibitor Fragment 6-22 amide (PKI 6-22) is a derivative of an active portion of the heat-stable cAMP-dependent protein kinase (PKA) inhibitor (PKI). It is a potent inhibitor of PKA.

Network states are often determined by modulators that alter the synaptic and cellular properties of the constituent neurons. Frequently neuromodulators act via second messengers, consequently their effects can persist. This persistence at the cellular/molecular level determines the maintenance of the

The minimal structure in the heat-stable inhibitor protein of cAMP-dependent protein kinase required for a low nanomolar potency of inhibition is the peptide Thr6-Tyr-Ala-Asp-Phe-Ile-Ala-Ser-Gly-Arg-Thr-Gly-Arg-Arg-Asn-Ala-+ ++Ile22-NH2 (PKI-(6-22)-amide). While primary structural determinants for interaction with the protein kinase are distributed throughout the

The chimeric DnaJ-PKAc enzymeresulting from an approximately 400-kb deletion of chromosome 19 is a primary contributor to the oncogenic transformation that occurs in fibrolamellar hepatocellular carcinoma, also called fibrolamellar carcinoma (FLC). This oncogenic deletion juxtaposes exon 1 of the DNAJB1
