| Abstract |
We studied the behavior of the signal recognition particle (SRP) components in Saccharomyces cerevisiae upon deficiencies of the protein transport caused by the absence of the SRP membrane receptor alpha-subunit. A decrease in the concentration of the SRP membrane receptor alpha-subunit in the cell significantly decreased the level of an SRP component, protein SRP72, as well as the levels of mRNAs of SRP protein components and the SRP receptor beta-subunit. But the amount of 7SL RNA remained unchanged. In contrast, in Escherichia coli cells the gradual decrease in the level of the protein FtsY (a homolog of the SRP membrane receptor alpha-subunit) was not associated with changes in the Ffh protein level. |
