STA — Solanum tuberosum

Summary

PGSC0003DMG401010374, designated STA and also known as MST8, is a potato gene on chromosome 3 that encodes a sugar transporter belonging to the major facilitator superfamily (MFS). The product possesses D-glucose and monosaccharide transmembrane transporter activity, functions as a symporter, and localises to the membrane and plasmalemma. STA is associated with glucose transmembrane transport, as well as with response to lectin, immune memory response, digestion, hypersensitivity, immune response, and protein phosphorylation. Studies of related genes in other species link the family to monosaccharide transport and stress responses, though these relationships are not directly established for potato.
