Mating System Homozygote x Homozygote (Female x Male) 01-MAR-06 Species laboratory mouse Generation ?+N1p (05-FEB-06) Donating Investigator Robert Ehlenfeldt, University of Minnesota Description
Mice that are homozygous for the transgene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Cerebellar Purkinje cell-specific tTA expression has been confirmed using PCR. Constitutive expression of tTA in Purkinje cells makes this strain suitable for creating bitransgenic mice that can, by withdrawing tetracycline (or its derivative doxycycline), inducibly express a gene of interest in Purkinje cells when the gene of interest is under the direction of a tetracycline-responsive element (TRE; tetO).Development
A transgenic construct using the Purkinje cell-specific murine Pcp2 regulatory region to direct expression of the tetracycline-regulated transactivator, tTA, was injected into FVB/N embryos. These embryos were implanted into pseudopregnant FVB/N females. Founder animals were backcrossed to FVB/N for five generations and were maintained by intercross.

| Allele Name | transgene insertion 3, Harry T Orr | ||
| Allele Type | Transgenic (random, expressed) | ||
| Mutation Made By | Harry Orr, University of Minnesota | ||
| Strain of Origin | FVB/N | ||
| Site of Expression | Expresses tTA in cerebellar Purkinje cells. | ||
| Expressed Gene | tTA, tetracycline-controlled transactivator, E. coli | ||
| The tetracycline-resistance gene (TetR), arose from chemically mutated Escherichia coli genome which was screened for tetracycline dependence (Gossen and Bujard, 1992). TetR was fused at the C-terminus with the viral co-activator, virion protein 16 of the herpes simplex virus (VP-16). The tetracycline-inhibitable transcription factor is a component of a bigenic system that allows doxycycline (a tetracycline analog) regulatable expression of genes that are under the direction of the tetracycline responsive promoter (TetOp)promoter. | |||
| Promoter | Pcp2, Purkinje cell protein 2 (L7), mouse, laboratory | ||
| General Note | Transgene mRNA levels in cerebella of mice of nine independent transgenic lines were assayed by Northern blot analysis of cerebellar extracts. The highest-expressing line was selected to cross with mice bearing a TetO-driven transgene. | ||
| Molecular Note | This transgene expresses the tetracycline transactivator (tTA) under control of the 5' sequences, including the first exon, the first intron and part of the second exon, of the Purkinje-cell specific mouse Purkinje cell protein 2 gene. [MGI Ref ID J:95453] | ||
