UniProtKB - Q291H8 (TRET1_DROPS)
Protein
Facilitated trehalose transporter Tret1
Gene
Tret1
Organism
Drosophila pseudoobscura pseudoobscura (Fruit fly)
Status
Functioni
Low-capacity facilitative transporter for trehalose. Does not transport maltose, sucrose or lactose. Mediates the bidirectional transfer of trehalose. Responsible for the transport of trehalose synthesized in the fat body and the incorporation of trehalose into other tissues that require a carbon source, thereby regulating trehalose levels in the hemolymph (By similarity).
