| molecularNote | Part of exons 2 and 3 are replaced with a neomycin resistance cassette. Northern blot analysis from brain confirmed the absence of transcript in homozygous mutant animals. The Y5 receptor, which resides in close proximity to the Y1 receptor, was unaffected by the gene targeting, as demonstrated by Northern analysis. |
