This transgene contains the coding sequence for enhanced yellow fluorescent protein (Venus), followed by a polyadenylation signal, inserted into the mouse genomic bacterial artificial chromosome (BAC) RP23-78P13 at the ATG transcription initiation codon of the corticotropin releasing hormone receptor 2 (Crhr2) gene so that expression of the reporter mRNA/protein is driven by the regulatory sequences of the mouse gene.
