MRS3/YJL133W Summary Help

Standard Name MRS3 1, 2
Systematic Name YJL133W
Feature Type ORF, Verified
Description Iron transporter, mediates Fe2+ transport across inner mito membrane; mitochondrial carrier family member; active under low-iron conditions; may transport other cations; MRS3 has a paralog, MRS4, that arose from the whole genome duplication (3, 4, 5, 6)
