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.
Exons 3 to 5 have been flanked by loxP sites (size of loxP-flanked region: 1.6 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 the exons 3 to 5 should result in the loss of function of the Cyp11b2 gene by deleting part of the catalytic domain and by generating a frameshift from exon 2 to exon 6 (premature Stop codon in exon 6).
According to NCBI and Ensembl databases, the Cyp11b1 gene (Entrez ID:110115 ; ENSMUSG00000075604) is located approx. 11 kb downstream of Cyp11b2 exon 5, in a tail-to-head orientation.
The corresponding conditional KO allele is available as line 11298.
