Displays increased levels of spontaneous RAD52 foci in proliferating diploid cells and exhibits an absence of G1 checkpoint in response to linoleic acid hydroperoxide (LoaOOH) treatment. Partially overlaps IDH2. Disruption phenotypes caused by deletion of this gene may also be a result of a defect in its overlapping gene. Product of a dubious gene prediction unlikely to encode a functional protein. Because of that it is not part of the S.cerevisiae S288c complete/reference proteome set.
