TPT — Solanum tuberosum
Summary
PGSC0003DMG400022832, designated TPT (also known as StTPT, APE2, or StAPE2) on potato chromosome 10, encodes a protein belonging to the TPT transporter family. The protein localizes to the chloroplast envelope and thylakoid membrane and has triose-phosphate antiporter activity with carboxylic acid and organophosphate ester transmembrane transporter activity. TPT is associated with triose phosphate and phosphoglycerate transport, regulation of photosynthesis and starch metabolism, including starch anabolism and breakdown, as well as sucrose anabolism and the pentose-phosphate shunt. The gene is associated with photosynthetic rate, carbohydrate and starch content, relative growth rate, and photosynthetic acclimation. Related genes in other species link the family to plant development, leaf development, root growth, DNA repair, and miRNA accumulation.
