a transgenic vector was constructed with the involucrin promoter vector which contained the first involucrin intron, an SV40 intron, a beta-galactosidase gene, and an SV40 polyadenylation site. Mouse cDNA encoding the full length of ZO-1 and Venus cDNA was replaced with the beta-galactosidase gene in the involucrin promoter vector.The promoter drives expression of a fusion between the gene and Venus reporter gene. One unnamed line was generated. (J:267304)
