Protein Kinase-A C-Alpha Definition

Expressed as 2 alternative isoforms (sperm-specific Isoform 2) by human PRKACA Gene (cAMP Ser/Thr Protein Kinase Family), Protein Kinase A C-Alpha is a catalytic subunit of tetrameric inactive cytoplasmic holoenzyme Protein Kinase A. Homo- or heterodimeric regulatory subunits of inactive PKA holoenzyme are associated with two catalytic subunits. Most cellular effects of cAMP are mediated through PKA. cAMP-induced dissociation of holoenzyme releases a dimer of cAMP-bound regulatory subunits and free monomeric catalytic subunits that serine/threonine phosphorylate many cytoplasmic and nuclear substrates.
