To achieve faithful replication of the genome once in each cell cycle, re-initiation of S-phase is prevented in G2 and origins are restricted from re-firing within S-phase. We have investigated the block to re-replication during G2 in fission yeast. The DNA synthesis that occurs when G2/M cyclin d...

During S-phase of the eukaryotic cell cycle, controls exist to ensure that replication origins fire only once and become inactivated after traverse of a replication fork. Failure of these controls results in local amplification of the genome which can lead to gene copy increases important for both ...

Protein concentrations evolve under greater evolutionary constraint than mRNA levels. In addition, translation efficiency of mRNA populations represents the chief determinant of basal protein concentrations. This raises a fundamental question as to how mRNA and protein levels are actively coordina...

The eukaryotic translation initiation factor 5B (eIF5B) is a homolog of the ancient IF2, a translation factor that facilitates initiator methionine-tRNAiMet (met-tRNAiMet) delivery to ribosomes in prokaryotes. IF2 evolved during early anaerobic cellular life and can be traced back to the last univer...

The journey by which proteins navigate their energy landscapes to their native structures is complex, involving (and sometimes requiring) many cellular factors and processes operating in partnership with a given polypeptide chain’s intrinsic energy landscape. The cytosolic environment and its compl...
