This transgene contains the coding sequence for enhanced green fluorescent protein (EGFP), followed by a polyadenylation signal, inserted into the mouse genomic bacterial artificial chromosome (BAC) RP23-392P11 at the ATG transcription initiation codon of the solute carrier family 32 (GABA vesicular transporter), member 1 gene (Slc32a1) so that expression of the reporter mRNA/protein is driven by the regulatory sequences of the mouse gene.
