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) RP23-63G6 at the ATG transcription initiation codon of the nuclear receptor co-repressor 1 (Ncor1) gene so that expression of the reporter mRNA/protein is driven by the regulatory sequences of the mouse gene.
