E.coli β-galactosidase was used as a reporter gene fused with the 3.9 kb promoter region in which transcription regulatory sequences and vitamin Dresponse element located. The eight amino acid residues at N-terminal ofβ-galactosidase were replaced with SV40 nuclear localization signal to distinguish from endogenousβ-galactosidase activity. The promoter drivedβ-galactosidase was discerned in nuclei of Purkinje cells in the cerebellum and distal renal tubes in the kidney. These expression pattern was compatible with the results obtained by immunocytochemistry with anti-Spot35 antibody. In this transgenic mouse the transgene expression was detected first on the tip of tail, limb buds and nose except for cerebellum, intestine and kidney where the protein is mainly present in adult. Immunohistochemical analyses against Spot35/calbindine antiserum showed coincident with the lacZ expression in these tissues. These findings might provide a new aspect concerning biological function of this protein in the early embryonic stages.}, pages = {67--75}, title = {マウス胎生期におけるカルビンジンD28k遺伝子の発現:レポーター遺伝子を用いたトランスジェニックマウスの解析}, volume = {112}, year = {1998} }
