-  Comments and Description Text from UniProtKB
  ID: KAP1_HUMAN
DESCRIPTION: RecName: Full=cAMP-dependent protein kinase type I-beta regulatory subunit;
FUNCTION: Regulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells.
SUBUNIT: The inactive holoenzyme is composed of two regulatory chains and two catalytic chains. Activation by cAMP releases the two active catalytic monomers and the regulatory dimer. Interacts with PRKX; regulates this cAMP-dependent protein kinase.
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.
PTM: The pseudophosphorylation site binds to the substrate-binding region of the catalytic chain, resulting in the inhibition of its activity.
SIMILARITY: Belongs to the cAMP-dependent kinase regulatory chain family.
SIMILARITY: Contains 2 cyclic nucleotide-binding domains.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
