MEF2D, a member of myocyte-specific enhancer binding factor 2 (MEF2) gene family, was shown by Northern blot hybridization to be strongly expressed in the head portion of mouse embryos at later stages of ontogenesis, in the cerebellum and the cerebrum of adult mice, in cultured cell lines of neuronal origin, and in skeletal and cardiac muscles. During(More)
By Northern blot analysis with the digoxigenin-labeled antisense RNA probes of the noncoding regions, the transcripts of three calmodulin (CaM) genes, CaMI, CaMII, and CaMIII, were separately detected in 12 different tissues of adult Wistar albino rats, without any cross-hybridization. The mRNAs of all three CaM genes were abundant in the central nervous(More)
Deletion analysis of the rat CaMII promoter demonstrated that the segment from -294 to +68 bases of CaMII was efficient as a promoter in NIH3T3 by transient assay. We developed transgenic mice carrying a fusion gene of this promoter segment and a beta-galactosidase reporter gene. This short CaMII promoter mediated the transgene expression in pyramidal cells(More)
Three non-allelic rat calmodulin (CaM) genes CaMI, CaMII and CaMIII, which share no homology in their 5'-upstream regions, are coordinately expressed in neurons of the central nervous system (CNS). Deletion analysis of the CaMIII promoter showed that the upstream segments longer than 700 bases functioned as efficient promoters, and that the sequence from(More)
Transgenic mice carrying a fused gene of the 294-base upstream and 68-base leader sequences of a rat calmodulin gene, CaMII, and beta-galactosidase gene were made. Only spermatocytes expressed the transgene mRNA in the testes of four independent transgenic lines. The localization of transgene mRNA was consistent with that of the mouse endogenous CaMII(More)
