A neo cassette replaced 3.2 kb of Mag1 genomic DNA, including most of exon 1 together with its ATG start codon as well as its upstream promoter region. This is a null allele of all three splice isoforms. Western blotting of the kidney cortex confirmed complete loss of Magi1 protein expression in the null mice. (J:237632)
