Role of Ado1p in the transcriptional response associated with AICAr supplementation


ABSTRACT: We investigated the role of Ado1p associated with AICAr supplementation on the global transcriptome of Y3188. The Y3188 strain was grown with or without AICAr. For each comparison, we made 2 biological replicates, swapping dyes.

5-Amino-4-imidazolecarboxamide ribonucleotide 5'-phosphate (AICAR) is a monophosphate metabolic intermediate of the de novo purine synthesis pathway that has highly promising metabolic and antiproliferative properties. Yeast mutants unable to metabolize AICAR are auxotroph for histidine. A screening for suppressors of this phenotype identified recessive and dominant mutants that result in lowering the intracellular AICAR concentration. The recessive mutants affect the adenosine kinase, which is  ...[more]
