Protein kinase A

Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

« Hide More detailed introduction

Cyclic AMP-mediated signalling involves regulation of cyclic nucleotide-gated ion channels, members of the Rap guanine nucleotide exchange family (Epac, ENSFM00250000000899) and activation of protein kinase A (PKA, also known as cyclic AMP-dependent protein kinase). PKA is a heterotetrameric enzyme composed of two regulatory and two catalytic subunits, which can be distinguished from Epac (exchange protein directly activated by cAMP, [2]) by differential activation by N6 benzyl-cAMP (see Table) and 8-pCPT-2'-O-Me-cAMP, respectively [3].
