UniProt functional annotation for Q3SX13



	UniProt functional annotation for Q3SX13

UniProt code: Q3SX13.

Organism: Bos taurus (Bovine).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Laurasiatheria; Artiodactyla; Ruminantia; Pecora; Bovidae; Bovinae; Bos.

Function: Extremely potent competitive inhibitor of cAMP-dependent protein kinase activity, this protein interacts with the catalytic subunit of the enzyme after the cAMP-induced dissociation of its regulatory chains. {ECO:0000250}.

Miscellaneous: The inhibitory site contains regions very similar to the hinge regions (sites that directly interact with the enzyme active site) and 'pseudosubstrate site' of the regulatory chains; but, unlike these chains, PKI does not contain cAMP-binding sites. The arginine residues within the inhibitory site are essential for inhibition and recognition of the enzyme active site (By similarity). {ECO:0000250}.

Similarity: Belongs to the PKI family. {ECO:0000305}.
