The targeting vector has been generated using C57BL/6J DNA and transfected into C57BL/6J ES cell line.
Mark3 exon 1 contains the translation initiation codon.
Exons 8-10 have been flanked by loxP sites.
The constitutive KO allele has been generated after Cre-mediated recombination by crossing chimeras to a Cre-Deleter on a C57BL/6 background.
The constitutive KO line has been subsequently backcrossed to C57BL/6NTac animals for at least 2 generations and the Cre-transgene was removed by segregation.
Deletions of exons 8-10 should result in loss of function of the Mark3 gene by generating a frameshift (premature stop codon in exon 11).
The remaining recombination sites are located in intron regions of the genome.
The corresponding conditional KO allele is available as line 8071.
Datamining and Design performed in 2005.
