The targeting vector has been generated using C57BL/6J DNA and transfected into C57BL/6N ES cell line.
Il13ra1 exon 1 contains the translation initiation codon.
Exon 3 has 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.
Deletion of exon 3 should result in loss of function of the Il13ra1 gene by generating a frame shift (premature stop codon in exon 4).
The remaining recombination sites are located in intron regions of the genome.
The constitutive KO line is also available in a mixed C57BL/6-129 Sv/Pas genetic background, line 7895.
Datamining and Design performed in 2005.
