Mutation detailsA neomycin resistance cassette replaced exons 3 through 7 of the gene. Northern blots of liver from homozygous mutant mice showed no detectable full-length transcript, but did show a smaller, truncated transcript when probes encompassing segments 5' or 3' to the deleted segment were used. Small amounts of truncated, but not intact, protein were detected in peritoneal macrophages from homozygous mutant mice. However, sera from homozygous mutant mice showed no detectable protein activity. (J:42679)
