Facts about cAMP-dependent protein kinase catalytic subunit beta.
Regulates the abundance of compartmentalized pools of its regulatory subunits via phosphorylation of PJA2 which binds and ubiquitinates these subunits, leading to their subsequent proteolysis (PubMed:12420224, PubMed:21423175). Phosphorylates GPKOW which modulates its ability to bind RNA (PubMed:21880142).

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.
Cytoplasm. Cell membrane. Membrane; Lipid-anchor. Nucleus. Translocates into the nucleus (monomeric catalytic subunit). The inactive holoenzyme is found in the cytoplasm.
