molecularNote | A PGK-neomycin resistance cassette replaced 0.8 kb of the gene including the translation initiation site and part of the signaling sequence. Plasma concentrations of fibronectin in heterozygotes were one-half those of wild-type littermates. The encoded protein was not detectable in immunoprecipitations from cultures of homozygous mutant E7.5 embryos. |
