Potential region of glutamine synthetase promoter driving astrocyte-specific transactivation, mediated by cerebellar granule cell membrane and glutamate has been identified by deletion analysis of promoter and transient transfection. The promoter region from -420 to -765 was found to be potentially important for this transactivation. These results provided further evidence for importance of neuronal-glial and glutamate-glial interactions in regulation of glial gene expression.
