OX NCBI_TaxID=10029; RN [1] RP SEQUENCE FROM N.A. RX MEDLINE=91244783; PubMed=1645343; RA Howard P., Day K.H., Kim K.E., Richardson J., Thomas J., Abraham I., RA Fleischmann R.D., Gottesman M.M., Maurer R.A.; RT "Decreased catalytic subunit mRNA levels and altered catalytic subunit RT mRNA structure in a cAMP-resistant Chinese hamster ovary cell line."; RL J. Biol. Chem. 266:10189-10195(1991). CC -!- FUNCTION: Phosphorylates a large number of substrates in the CC cytoplasm and the nucleus. CC -!- CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. CC -!- ENZYME REGULATION: Activated by cAMP. CC -!- SUBUNIT: A number of inactive tetrameric holoenzymes are produced CC by the combination of homo- or heterodimers of the different CC regulatory subunits associated with two catalytic subunits. cAMP CC causes the dissociation of the inactive holoenzyme into a dimer of CC regulatory subunits bound to four cAMP and two free monomeric CC catalytic subunits. CC -!- SUBCELLULAR LOCATION: Cytoplasmic (inactive holoenzyme and CC monomeric catalytic subunit). Translocates into the nucleus CC (monomeric catalytic subunit) (By similarity). CC -!- TISSUE SPECIFICITY: Ubiquitously expressed in mammalian tissues. CC -!- PTM: Asn-2 is partially deaminated to Asp-2 giving rise to 2 CC major isoelectric variants, called CB and CA respectively (By CC similarity). CC -!- SIMILARITY: Belongs to the Ser/Thr protein kinase family. cAMP CC subfamily.
