Abstract excerpt
To elucidate SUMO-1 functions in vivo, we targeted by homologous recombination the last three exons of the murine Sumo-1 gene. Sumo-1 mRNA abundance was reduced to one-half in heterozygotes and was undetectable in Sumo-1(-/-) mice, and SUMO-1-conjugated RanGAP1 was detectable in wild-type mouse embryo fibroblasts (MEFs) but not in Sumo-1(-/-) MEFs, indicating that gene targeting yielded Sumo-1-null mice. Sumo-1...
