title: The ldb1 mutant of Saccharomyces cerevisiae is defective in Pmr1p, the yeast secretory pathway/Golgi Ca(2+)/Mn(2+)-ATPase.
abstract: The LDB1 gene of Saccharomyces cerevisiae was identified by complementation of the ldb1 mutant phenotype with a genomic library. We found that the ldb1 defect is complemented by PMR1 which codes for the yeast secretory pathway/Golgi Ca(2+)/Mn(2+)-ATPase. Besides that, the analysis of a null mutation of the PMR1 gene revealed a phenotype identical to that of ldb1 mutant. Thus, LDB1 must be considered a synonym of PMR1.
