Rabbit anti-Human PRKACB Polyclonal Antibody

Uniprot Id

P22694

Target Species

Human

Target Name

PRKACB

Target Full Name

cAMP-dependent protein kinase catalytic subunit beta

Target Function

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. Phosphorylates GPKOW which regulates its ability to bind RNA.

Target Subcellular Location

Cytoplasm. Cell membrane. Membrane; Lipid-anchor. Nucleus.

Target Protein Families

Protein kinase superfamily, AGC Ser/Thr protein kinase family, cAMP subfamily

Target Tissue Specificity

Isoform 1 is most abundant in the brain, with low level expression in kidney. Isoform 2 is predominantly expressed in thymus, spleen and kidney. Isoform 3 and isoform 4 are only expressed in the brain.

Target Synonyms

Target Background

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.
