Integral plasma membrane protein and eisosome component; GFP-fusion protein is more abundant at MCCs (membrane compartment occupied by Can1) in the presence of glycerol and oleate; GFP-fusion protein is induced in response to the DNA-damaging agent MMS; slight defects in sporulation and altered plasma membrane sphingolipid composition; SUR7 family member; YNL194C has a paralog, FMP45, that arose from the whole genome duplication
