PKIA antibodies are validated for multiple techniques, with dilution protocols optimized per application:
Recent studies utilizing PKIA antibodies highlight its regulatory roles:
PKA Inhibition: PKIA suppresses PKA activity by sequestering catalytic subunits, impacting phosphorylation of CREB and β-catenin .
Mitochondrial Dynamics: Reduced PKIA expression increases ER calcium stores via DRP1 phosphorylation, influencing mitochondrial fission .
Disease Associations: Elevated PKIA levels correlate with cancer progression and metabolic disorders in murine models .
This antibody serves as an exceptionally potent competitive inhibitor of cAMP-dependent protein kinase activity. It interacts directly with the catalytic subunit of the enzyme following the cAMP-induced dissociation of its regulatory chains.
