The targeting vector has been generated using C57BL/6J DNA and transfected into TaconicArtemis C57BL/6NTac ES cell line.
Exon 1 contains the translation initiation codon.
Exon 2 has been flanked by loxP sites (size of loxP-flanked region: 0.8 kb).
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 derived using C57BL/6NTac animals and the Cre-transgene was removed by segregation.
Deletion of exon 2 should result in loss of function of the Arrb2 gene by generating a frameshift from exon 1 to exons 3-7 (premature Stop codon in exon 3).
The remaining recombination sites are located in non-conserved regions of the genome.
Datamining and Design performed in 2009.
