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) RP23-177E2 at the ATG transcription initiation codon of the Ly6/Plaur domain containing 2 gene (Lypd2; formerly 0610005K03Rik) so that expression of the reporter mRNA/protein is driven by the regulatory sequences of the mouse gene.
