| molecularNote | A genomic fragment containing exon 1 and part of intron 1 was replaced with a neomycin selection cassette. The deleted sequences encode 237 amino acids from the N-terminal region of the corresponding protein. Western blot analysis on kidney membranes derived from homozygous mice demonstrated that no detectable protein is produced from this allele. |
