cAMP-Dependent Protein Kinase Catalytic Subunit Beta - CISMeF
CAMP-Dependent Protein Kinase Catalytic Subunit BetaNCIt concept
Preferred Label : cAMP-Dependent Protein Kinase Catalytic Subunit Beta;
NCIt synonyms : cAMP-Dependent Protein Kinase Beta-Catalytic Subunit; cAMP-Dependent Protein Kinase Beta; PKA C-Beta; PRKACB; EC 2.7.11.11; Protein Kinase A C-Beta; Protein Kinase-A C-Beta;
NCIt definition : cAMP-dependent protein kinase catalytic subunit beta (351 aa, 41 kDa) is encoded
by the human PRKACB gene. This protein is involved in both protein phosphorylation
and cAMP-mediated signal transduction.;
NCIt note : cAMP-dependent protein kinase catalytic subunit gamma 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.;
