| molecularNote | A targeting construct was designed to insert a G to T nucleotide transversion into exon 1. This mutation converts codon 5 from a glycine to a stop codon (G5X). Expression of the alpha5(IV) chain was lost in mutant kidneys from males. Basement membrane expression of the alpha 3(IV) chain was lost as well as that of the alpha6(IV) chain. Expression of alpha1(IV) and alpha2(IV) was conserved. Expression of the alpha5(IV) and alpha3(IV) chains in kidneys from females was mosaic, reflecting X-inactivation. |
