The PKA α/β CAT (Phospho-Thr197) antibody is designed to detect the catalytic subunits (α and β isoforms) of protein kinase A (PKA) when phosphorylated at threonine 197 (Thr197). PKA, a critical serine/threonine kinase, regulates diverse cellular processes, including metabolism, gene expression, and apoptosis, via cAMP-dependent signaling. The catalytic subunits (PKA-Cα and PKA-Cβ) become active upon dissociation from regulatory subunits in response to elevated cAMP levels.
Phosphorylation at Thr197 in the catalytic domain is essential for PKA activity, as it stabilizes the active conformation and ensures proper substrate recognition. This post-translational modification occurs autocatalytically during PKA activation or via upstream kinases, such as PDK1. depending on cellular context. The antibody specifically recognizes this phosphorylated epitope, enabling researchers to study PKA activation status in various biological settings.
Applications include Western blotting, immunofluorescence, and immunohistochemistry to investigate PKA signaling dynamics in diseases like cancer, cardiovascular disorders, and neurological conditions. Validation typically involves testing in cell lines with known PKA activation or inhibition (e.g., forskolin or H89 treatment) to confirm specificity. Cross-reactivity with non-phosphorylated forms or other kinases is generally minimal, but isoform specificity (α vs. β) should be verified experimentally. This antibody serves as a vital tool for dissecting cAMP/PKA pathways in both physiological and pathological states.
