Involved in the import of GDP-mannose from the cytoplasm into the Golgi lumen. Recycles between the Golgi apparatus and the endoplasmic reticulum. Belongs to the TPT transporter family. SLC35D subfamily. This is a truncated version of GDP-mannose transporter 2. This strain has a stop codon in position 73, which disrupts the gene coding for this protein and produces two ORFs. A contiguous sequence for GDP-mannose transporter 2 can be found in strain Lalvin EC1118 (AC C8Z742).
