co-expression of Doa4p with cyk-3 of Caenorhabditis elegans and ubiquitin-beta-galactosidase fusion protein in Escherichia coli Saccharomyces cerevisiae

additional information
-
Saccharomyces cerevisiae
additional information gene cyk-3 null mutants are lethal, mutants fail to polarize the actin cytoskeleton, to segregate germline determinants, to assemble an intact cleavage furrow, and are intrinsically defective in osmotic regulation and cytokinesis, the latter defect can be partially rescued by providing osmotic support Caenorhabditis elegans
