UniProt Comments
Responsible for the transport of sucrose into the cell, with the concomitant uptake of protons (symport system). Can also transport other glucosides such as maltose, salicin, helicin, and alpha-phenylglucoside. Probably required for apoplastic phloem sucrose loading in source tissues (e.g. leaves) in order to transport it to sink tissues (e.g. roots, flowers). Probably not involved in transport of sugars across the symplastic discontinuity between the endosperm and the embryo. Essential for normal pollen germination, but not for pollen maturation or starch accumulation in pollen.
