Systematic name YDR050C
Gene name TPI1
Aliases
Feature type ORF, Verified
Coordinates Chr IV:556472..555726
Primary SGDID S000002457


Description of YDR050C: Triose phosphate isomerase, abundant glycolytic enzyme; mRNA half-life is regulated by iron availability; transcription is controlled by activators Reb1p, Gcr1p, and Rap1p through binding sites in the 5' non-coding region; inhibition of Tpi1p activity by PEP (phosphoenolpyruvate) stimulates redox metabolism in respiring cells; E104D mutation in human TPI causes a rare autosomal disease[1][2][3][4][5]
