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 3 has been flanked by loxP sites (size of loxP-flanked region: 1.3 kb).
The conditional KO allele has been generated after Flp-mediated recombination by crossing chimeras to a Flp-Deleter on a C57BL/6 background.
The conditional KO line has been derived using C57BL/6NTac animals and the Flp-transgene was removed by segregation.
The constitutive KO allele can be generated by Cre-mediated recombination. Deletion of exon 3 should result in loss of function of the Opcml gene by deleting most part of the Immunoglobulin V-set domain and by generating a frameshift from exon 2 to exons 4-6 (premature Stop codon in exon 4).
The remaining recombination sites are located in non-conserved regions of the genome.
