cAMP is a general second messenger. Three classes of proteins feeling cAMP concentrations by cyclic nucleotide binding (CNB) domains in mammalians1,2. They are proteins kinase A (PKA), ion stations with CNB domains and Epac protein. The appearance of ion stations with CNB domains is principally limited to the center and the visible and olfactory program.… Continue reading cAMP is a general second messenger.
