Cytotoxic Necrotizing Factors and Rho GTPase Activation in Bacterial Toxins

Cytotoxic necrotizing factors (CNFs) are bacterial exotoxins that have attracted significant attention due to their ability to modify host cell functions by targeting Rho GTPases. These small, ...

General amino acid control in fission yeast is regulated by a nonconserved transcription factor, with functions analogous to Gcn4/Atf4

Eukaryotes respond to amino acid starvation by enhancing the translation of mRNAs encoding b-ZIP family transcription factors (GCN4 in Saccharomyces cerevisiae and ATF4 in mammals), which launch ...

Posttranslational regulation of multiple clock-related transcription factors triggers cold-inducible gene expression in Arabidopsis

Cold stress is an adverse environmental condition that affects plant growth, development, and crop productivity. Under cold stress conditions, the expression of numerous genes that function in the ...
