P2 receptors are membrane-bound receptors for extracellular nucleotides such as for example ATP and UTP. Phosphorylated MLC20 was improved by ATP and UTP treatment. To conclude, esophageal contraction induced by ATP and UTP was preferentially mediated by P2Y receptors combined to Gi3 and G q proteins, which activate PLC1 and PLC3. Subsequently, improved intracellular Ca2+… Continue reading P2 receptors are membrane-bound receptors for extracellular nucleotides such as for
