The targeting vector has been generated using C57BL/6J DNA and transfected into C57BL/6J ES cell line.
Hao2 exon 3 contains the translation initiation codon.
Exon 5 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 5 should result in loss of function of the Hao2 gene by deleting essential domains of the protein and inducing a frameshift (premature stop codon in exon 6).
The remaining recombination sites are located in intron regions of the genome.
Datamining and Design performed in 2005.
