Amino acid signaling in yeast: casein kinase I and the Ssy5 endoprotease are key determinants of endoproteolytic activation of the membrane-bound Stp1 transcription factor.

Abstract excerpt

Saccharomyces cerevisiae cells possess a plasma membrane sensor able to detect the presence of extracellular amino acids and then to activate a signaling pathway leading to transcriptional induction of multiple genes, e.g., AGP1, encoding an amino acid permease. This sensing function requires the permease-like Ssy1 and associated Ptr3 and Ssy5 proteins, all essential to activation, by endoproteolytic processing,...
