Belongs to the ThrE exporter (TC 2.A.79) family. This is a truncated version of a ThrE family protein. Strain S288c has a frameshift in position 382, which disrupts the gene coding for this protein and produces two ORFs YJL107C and YJL108C. A contiguous sequence for a S.cerevisiae ThrE family protein can be found in strain YJM789 (AC A6ZQL9).
