PROSITE documentation PDOC00004

cAMP- and cGMP-dependent protein kinase phosphorylation site


There has been a number of studies relative to the specificity of cAMP- and cGMP-dependent protein kinases [1,2,3]. Both types of kinases appear to share a preference for the phosphorylation of serine or threonine residues found close to at least two consecutive N-terminal basic residues. It is important to note that there are quite a number of exceptions to this rule.
