ATO2/YNR002C Summary Help

Standard Name ATO2 1
Systematic Name YNR002C
Alias FUN34 2
Feature Type ORF, Verified
Description Putative transmembrane protein involved in export of ammonia; ammonia is a starvation signal that promotes cell death in aging colonies; phosphorylated in mitochondria; member of the TC 9.B.33 YaaH family; homolog of Y. lipolytica Gpr1p; ATO2 has a paralog, ADY2, that arose from the whole genome duplication (1, 3, 4, 5, 6, 7)
Name Description Ammonia (Ammonium) Transport Outward 1
