Protein of unknown function; encodes new type of domain, which ab initio modeling suggests is predominantly alpha-helical; nonessential for growth, deletion increases sensitivity to osmostress; expressed at moderate to high abundance; ORF also present in strains EC1118, YJM789, RM11-1a, and AWRI1631; Gln24 in S288C reference is substituted with Arg in wine strain EC1118; predicted S-palmitoylation site on Cys2, suggesting membrane association; transcript previously mischaracterized as SUT646
