Constitutive signal transduction by mutant Ssy5p and Ptr3p components of the SPS amino acid sensor system in Saccharomyces cerevisiae.

Eukaryotic cell - 1 Jun 2005

Poulsen Peter, Wu Boqian, Gaber Richard F, Kielland-Brandt Morten C

Abstract excerpt

Amino acids in the environment of Saccharomyces cerevisiae can transcriptionally activate a third of the amino acid permease genes through a signal that originates from the interaction between the extracellular amino acids and an integral plasma membrane protein, Ssy1p. Two plasma membrane-associated proteins, Ptr3p and Ssy5p, participate in the sensing, which results in cleavage of the transcription factors...
