Abstract excerpt
When prespore cells approach the top of the stalk in a Dictyostelium fruiting body, they rapidly encapsulate in response to the signalling peptide SDF-2. Glutamate decarboxylase, the product of the gadA gene, generates GABA from glutamate. gadA is expressed exclusively in prespore cells late in development. We have found that GABA induces the release of the precursor of SDF-2, AcbA, from prespore cells. GABA also...
