FPS1/YLL043W Summary Help

Standard Name FPS1 1
Systematic Name YLL043W
Feature Type ORF, Verified
Description Aquaglyceroporin, plasma membrane channel; involved in efflux of glycerol and xylitol, and in uptake of acetic acid and the trivalent metalloids arsenite and antimonite; role in mediating passive diffusion of glycerol is key factor in maintenance of redox balance; member of major intrinsic protein (MIP) family; phosphorylated by Hog1p MAPK under acetate stress; deletion improves xylose fermentation (2, 3, 4, 5, 6, 7)
