ISU2/YOR226C Summary Help

Standard Name ISU2 1
Systematic Name YOR226C
Alias NUA2
Feature Type ORF, Verified
Description Protein required for synthesis of iron-sulfur proteins; localized to the mitochondrial matrix; performs a scaffolding function in mitochondria during Fe/S cluster assembly; involved in Fe-S cluster assembly for both mitochondrial and cytosolic proteins; isu1 isu2 double mutant is inviable; protein abundance increases in response to DNA replication stress; evolutionarily conserved; ISU2 has a paralog, ISU1, that arose from the whole genome duplication (1, 2, 3, 4, 5)
Name Description IscU homolog 1
