Control of ACA dependent genes. A set of at least 13 developmental genes are only expressed if the gene for ACA is wild type. The signal transduction pathway from the extracellular cAMP signal to transcriptional control is almost the same as that in the PKA oscilatory circuit (Fig. 6) but requires the robust synthesis of cAMP that ACA can provide following a pulse of extracellular cAMP. It is possible that transcription of these genes depends on higher levels of PKA than the pulse induces genes.
