We have examined the feasibility and efficiency of PCR-mediated direct gene disruptions in the fission yeast Schizosaccharomyces pombe. In the present study, the S.pombe ura4+ gene was amplified by PCR with oligonucleotides that had short flanking regions ( approximately 40 bp) to the target gene. Using this purified PCR product we were able to disrupt(More)
The intracellular fates of membrane and secretory immunoglobulin heavy chains were examined in a pre-B cell line that has switched to the gamma isotype. The membrane form of the heavy chain (gamma m) was rapidly degraded while the secretory form (gamma s) was retained intracellularly in association with BiP. The degradation of gamma m could not be inhibited(More)
