WebMar 27, 2024 · Emerging evidence supports a relevant role for Epac, a guanine nucleotide-exchange factor for the small GTPases Rap1 and Rap2, 17 - 20 as a mediator of cAMP signalling in the heart and a regulator of Ca 2+ signalling/contractility. 21 Two cardiac Epac isoforms have been identified. Webincrease is seen in other subcellular compartments. A possible explanation involves signal transduction. In terms of protein numbers, signal transduction pathways may be roughly described as a pyramid with an expansive base in the extracellular domain (the numerous extracellular signal proteins), progressively
