CC -!- FUNCTION: Regulatory subunit of the cAMP-dependent protein kinases
CC involved in cAMP signaling in cells. {ECO:0000250}.
CC -!- SUBUNIT: The inactive holoenzyme is composed of two regulatory chains
CC and two catalytic chains. Activation by cAMP releases the two active
CC catalytic monomers and the regulatory dimer. Interacts with PRKACA and
CC PRKACB (By similarity). PRKAR1A also interacts with RFC2; the complex
CC may be involved in cell survival. Interacts with AKAP4. Interacts with
CC RARA; the interaction occurs in the presence of cAMP or FSH and
CC regulates RARA transcriptional activity. Interacts with the
CC phosphorylated form of PJA2. Interacts with CBFA2T3. Interacts with
CC PRKX; regulates this cAMP-dependent protein kinase (By similarity).
CC Interacts with smAKAP; this interaction may target PRKAR1A to the
CC plasma membrane. Interacts with AICDA (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:P10644}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Four types of regulatory chains are found: I-alpha,
CC I-beta, II-alpha, and II-beta. Their expression varies among tissues
CC and is in some cases constitutive and in others inducible.
CC -!- PTM: The pseudophosphorylation site binds to the substrate-binding
CC region of the catalytic chain, resulting in the inhibition of its
CC activity.
CC -!- SIMILARITY: Belongs to the cAMP-dependent kinase regulatory chain
CC family. {ECO:0000305}.
