Previous GeneCards Identifiers for PRKACB Gene
The protein encoded by this gene is a member of the serine/threonine protein kinase family. The encoded protein is a catalytic subunit of cAMP (cyclic AMP)-dependent protein kinase, which mediates signalling though cAMP. cAMP signaling is important to a number of processes, including cell proliferaton and differentiation. Multiple alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2014]
GeneCards Summary for PRKACB Gene
PRKACB (Protein Kinase CAMP-Activated Catalytic Subunit Beta) is a Protein Coding gene. Diseases associated with PRKACB include Carney Complex Variant and Primary Pigmented Nodular Adrenocortical Disease. Among its related pathways are Signaling in Gap Junctions and Aquaporin-mediated transport. GO annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase activity. An important paralog of this gene is PRKACA.
UniProtKB/Swiss-Prot for PRKACB Gene
Mediates cAMP-dependent signaling triggered by receptor binding to GPCRs. PKA activation regulates diverse cellular processes such as cell proliferation, the cell cycle, differentiation and regulation of microtubule dynamics, chromatin condensation and decondensation, nuclear envelope disassembly and reassembly, as well as regulation of intracellular transport mechanisms and ion flux. Regulates the abundance of compartmentalized pools of its regulatory subunits through phosphorylation of PJA2 which binds and ubiquitinates these subunits, leading to their subsequent proteolysis.
Protein kinase A (PKA, aka cAMP-dependent protein kinase) is involved in the regulation of lipid and glucose metabolism and is a component of the signal transduction mechanism of certain GPCRs. PKA is composed of two regulatory subunits and two catalytic subunits.
