N2 - The phenomenon of nonsense suppression, which leads to the stop codons reading-through, may be related to disturbances in the operation of various components of the translation apparatus and the proteins interacting with them. The phosphatase Ppzlp is one of the factors affecting the nonsense suppression efficiency in Saccharomyces yeast. In this work, the impact of the overexpression of gene PPZ1 and its mutant allele PPZ1-R451L on the phenotypic expression of various mutant alleles of genes SUP35 and SUP45 or the yeast prion [PSI +] was analyzed. On the basis of the data obtained, a suggestion about the possible role of proteins Sup35p and Sup45p in the processes mediating the influence of gene PPZ1 overexpression on the efficiency of nonsense suppression is made.
