General annotation (Comments)
| Function | Regulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells. Type II regulatory chains mediate membrane association by binding to anchoring proteins, including the MAP2 kinase By similarity. |
| Subunit structure | The inactive form of the enzyme is composed of two regulatory chains and two catalytic chains. Activation by cAMP produces two active catalytic monomers and a regulatory dimer that binds four cAMP molecules. Interacts with AKAP4 and CBFA2T3 By similarity. Interacts with the phosphorylated form of PJA2 By similarity. |
| Subcellular location | Cytoplasm By similarity. Cell membrane By similarity. Note: Co-localizes with PJA2 in the cytoplasm and the cell membrane By similarity. |
| Tissue specificity | Four types of regulatory chains are found: I-alpha, I-beta, II-alpha, and II-beta. Their expression varies among tissues and is in some cases constitutive and in others inducible. |
| Post-translational modification | A second phosphorylation site has not been located. Phosphorylation of Thr-212 by PDPK1 seems to attenuate the activity of PKA, perhaps by strengthening interaction between the regulatory and the catalytic subunits. |
| Sequence similarities | Belongs to the cAMP-dependent kinase regulatory chain family. Contains 2 cyclic nucleotide-binding domains. |
