| molecularNote | Exon 4 was flanked by loxP sites and a FRT-flanked neomycin selection cassette was inserted downstream of the second loxP site. Flp-mediated recombination removed the selection cassette. Cre-mediated recombination deleted exon 4. Absence of protein was confirmed by receptor binding assay. |
