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) RP24-155F20 at the ATG transcription initiation codon of the calcium channel, voltage-dependent, T type, alpha 1G subunit (Cacna1g) gene so that expression of the reporter mRNA/protein is driven by the regulatory sequences of the mouse gene.
