Systematic name YDR172W
Gene name SUP35
Aliases GST1, PNM2, SAL3, SUF12, SUP2, SUP36, [PSI(+)], [PSI]
Feature type ORF, Verified
Coordinates Chr IV:808324..810381
Primary SGDID S000002579

Description of YDR172W: Translation termination factor eRF3, has a role in mRNA deadenylation and decay; altered protein conformation creates the [PSI(+)] prion that alters translational fidelity and results in a nonsense suppressor phenotype[1][2][3][4]
