2 If verification has not been performed (as indicated by "NO"), investigators may request specific verification testing for a fee. Requests should be submitted directly to the MMRRC Distribution Center assigned to the management, archiving, and distribution of the strain. A full listing of available testing and analytical services is available at https://www.mmrrc.org/about/services.php.

Genetic Alterations
Taf1PC-XDP knock-in (KI) mice harbor a loxP site in intron 24 of the endogenous Taf1 locus, a marker cassette that includes mNeonGreen sequence, driven by a human EEF1A1 promoter, and a second loxP site followed by human TAF1 gene sequence from intron 24 through the 3' UTR, including the SVA_F retrotransposon containing 34 hexanucleotide repeats.

Prior to Cre-mediated recombination, these Taf1PC-XDP mice will express wildtype mouse Taf1 protein, green fluorescent protein as well as human HPRT1 and a NeoR selectable marker. When bred to a tissue-specific Cre recombinase strain, resulting offspring will express a fusion of mouse Taf1 exons 1-24 with human TAF1 exons 25-38 including the SVA-F retrotransposon, in cre-expressing tissues.
ES Cell Line
MK6 derived from C57BL/6J
Phenotype

Homozygous Taf1PC-XDP KI females and hemizygous Taf1PC-XDP males are viable and fertile, with no overt phenotype.

Conditional phenotype: Prior to Cre-mediated recombination, these Taf1PC-XDP mice express wildtype mouse TAF1 protein and green fluorescent protein as well as human HPRT1 and a NeoR selectable marker. When bred to a tissue-specific Cre recombinase strain, recombination occurs between the loxP site in mouse Taf1 intron 24 and the second loxP site that precedes the human TAF1 intron 24, resulting in expression of a fusion of mouse Taf1 exons 1-24 with human TAF1 exons 25-38 including the intronic SVA_F retrotransposon, in cre-expressing tissues.

When crossed to a Nestin-Cre mouse line (RRID:IMSR_JAX:003771) and resulting progeny demonstrated reduced body weight, progressive decline in motor function and coordination, kyphosis, tremors and hindlimb dragging by 3-4 weeks of age. The NestinCreTaf1XDP male mice did not survive beyond 60 days of age and brain histopathology demonstrated enlarged lateral ventricles as well as significant neurodegeneration in the striatum and hippocampus. The NestinCreTaf1XDP heterozygous female mice did not display any of these phenotypes and had a normal lifespan.

The submitting investigator notes that although Taf1PC-XDP ESCs are visibly green under UV light, GFP expression has not been evaluated by either direct fluorescence or by immunohistochemistry methods in the mouse tissues.

The Taf1PC-XDP KI mice may be useful for studying X-linked dystonia-parkinsonism.

To request gene-specific and other genotyping services for a strain, please contact the distribution MMRRC Center for more information.

Background Genetic Quality:

The MMRRC has developed a Genetic Quality Control pipeline using the MiniMUGA array to provide additional information to identify and validate genetic backgrounds of MMRRC strains. For more information on whether genetic background data is available, please contact MMRRC_GeneticQC@med.unc.edu. Note: that MiniMUGA genetic background data is not available on all strains, but can be ordered if desired.

Strain Development
Using CRISPR/Cas9-techology, the Taf1PC-XDP knock-in (KI) mice were designed to insert an initial loxP site into intron 24 of the endogenous TATA-box binding protein associated factor 1 (Taf1) locus. After which a marker cassette, and a second loxP site, are followed by human TAF1 genomic sequence from intron 24 through the 3' UTR, including the XDP-associated SVA_F retrotransposon containing 34 contiguous hexanucleotide repeats, were introduced via homologous recombination. The marker cassette includes a human eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) promoter, mNeonGreen sequence, a human mini hypoxanthine phosphoribosyltransferase 1 (HPRT1) gene, T2A self-cleaving peptide sequence, a neomycin resistance gene, and a Simian virus 40 PolyA (SV40pA) sequence.
  • There is also a STOP codon in the marker cassette (in NeoR), as well as the native STOP codon in human TAF1 exon 38.
  • TAF1 human coding exons 25-38 have been engineered as needed to code for a fully mouse TAF1 protein.

The Taf1PC-XDP KI construct was electroporated into MK6 C57BL/6J-derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and the resulting chimeric males were bred to B6N-Tyrc-Brd/BrdCrCrl females (B6-Albino, Charles River). These mice were then backcrossed to C57BL/6J background for at least 3 generations by the donating laboratory. Upon arrival at The Jackson Laboratory, mice were bred to C57BL/6J inbred mice (Stock No. 000664) for at least one generation before hemizygous sperm was frozen.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
