ERK inhibition of long isoforms is regulated by a unique feedback control whereby elevated cAMP levels cause PKA (protein kinase A) to phosphorylate UCR1 and ablate the inhibitory action of ERK. PDE4 isoforms can also be found in complex with beta-arrestins where they provide a novel part of the cellular desensitization mechanism to receptor-mediated cAMP signalling. Stimulation of the beta(2)-adrenoceptor recruits beta-arrestins with bound PDE4, delivering an enzyme capable of degrading cAMP at its site of synthesis at the plasma membrane a major role of recruited PDE4 is to regulate plasma membrane PKA activity involved in phosphorylating the beta(2)-adrenoceptor. Recruited PDE4 thus desensitizes the ability of the beta(2)-adrenoceptor to activate ERK via G(i) inhibition of Raf1 functioning can be achieved through its phosphorylation by PKA" ?g. }
