Camp signaling in subcellular compartments
WebSignaling through cAMP regulates most cellular functions. The spatiotemporal control of cAMP is, therefore, crucial for differential regulation of specific cellular targets. Here we investigated the consequences of PDE4B or PDE4D gene ablation on cAMP signaling at a subcellular level using mouse embryonic fibroblasts. 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.
