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.

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 the phosphorylated form of PJA2 By similarity. Ref.8

Subcellular location

Cytoplasm By similarity. Cell membrane By similarity. Note: Colocalizes with PJA2 in the cytoplasm and at 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

Phosphorylated by the activated catalytic chain.

Sequence similarities

Belongs to the cAMP-dependent kinase regulatory chain family.

Contains 2 cyclic nucleotide-binding domains.
