-
The targeting vector has been generated using C57BL/6J DNA and transfected into C57BL/6NTac ES cell line.
-
Numb exon 1 contains the translation initiation codon.
-
Exons 4-5 have been flanked by loxP sites.
-
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 subsequently backcrossed to C57BL/6NTac animals for at least 2 generations and the Flp-transgene was removed by segregation.
-
The constitutive KO allele can be generated by Cre-mediated recombination. Deletion of exons 4-5 should result in loss of function of the Numb gene by deletion of the Phospho Tyrosine binding domain.
-
The remaining recombination sites are located in intron regions of the genome.
