This transgene contains the promoter of the rat bone gamma-carboxyglutamate (gla) protein gene (Bglap; also called osteocalcin, Oc) upstream of sequence encoding a MYC epitope tag joined in-frame to a cDNA encoding mouse osteomodulin (also called osteoadherin, OSAD), which is interrupted between the first and second exon sequences by the rabbit beta-globin intron and is followed by the SV40 polyadenylation signal.
