Protein kinase A - Wikipedia
Protein kinase A, more precisely known as adenosine 3',5'-monophosphate (cyclic AMP)-dependent protein kinase, abbreviated to PKA, was discovered by chemists Edmond H. Fischer and Edwin G. Krebs in 1968.

Protein kinase A (PKA) is a key regulator of cellular functions by selectively phosphorylating numerous substrates, including ion channels, enzymes, and transcription factors. It has long served as a model system for understanding the eukaryotic kinases.
Physiological and pathological roles of protein kinase A in the heart
Protein kinase A (PKA) is a central regulator of cardiac performance and morphology. Myocardial PKA activation is induced by a variety of hormones, neurotransmitters, and stress signals, most notably catecholamines secreted by the sympathetic nervous system.

Among these general cellular mechanisms, the cAMP-dependent protein kinase (protein kinase A, PKA) signaling pathway in CA1 stands out for several reasons.
Protein Kinase A - Colorado State University
Like other protein kinases, protein kinase A (also known as the cyclic AMP-dependent protein kinase or A kinase) is an enzyme that covalently decorates proteins with phosphate groups. The unique characteristic of protein kinase A is that its activity is regulated by fluctuating levels of cyclic AMP within cells (hence its alias as the cyclic ...

The Tails of Protein Kinase A - PubMed
Protein kinase A (PKA) is a holoenzyme consisting of a regulatory (R)-subunit dimer and two catalytic (C)-subunits. There are two major families of C-subunits, C α and C β, and four functionally nonredundant R-subunits (RI α, RI β, RII α, RII β).
