Almost completely overlaps VMA9. Product of a dubious gene prediction unlikely to encode a functional protein. Was originally (PubMed:7992502) thought to function in calcofluor white resistance, hence the name CWH36, but this phenotype was later (PubMed:14594803) attributed to the overlapping gene VMA9. Because of that it is not part of the S.cerevisiae S288c complete/reference proteome set.
