GPT1_ARATH developmental stage Expressed during the transient accumulation of starch in the developing seeds. Decline rapidly 8 days after flowering. Not detected in mature seeds.
GPT1_ARATH function Glucose 6-phosphate (Glc6P) transporter (PubMed:15722468). Transports also inorganic phosphate, 3-phosphoglycerate, triose phosphates and, to a leser extent, phosphoenolpyruvate (PubMed:15722468). Responsible for the transport of Glc6P into plastids of heterotrophic tissues where it can be used as a carbon source for starch biosynthesis, as substrate for fatty acid biosynthesis or as substrate for NADPH generation via the oxidative pentose phosphate pathway (OPPP) (PubMed:15722468). Required for pollen maturation and embryo sac development (PubMed:15722468, PubMed:20659277). Preferentially exchanges Glc6P for ribulose-5-phosphate (Ru5P) in reconstituted yeast proteoliposomes (PubMed:32111666). May supply the substrate (Glc6P) for OPPP reactions inside peroxisomes and exchange it with the product Ru5P which leaves the organelle (PubMed:32111666).
GPT1_ARATH similarity Belongs to the TPT transporter family. GPT (TC 2.A.7.9) subfamily.
GPT1_ARATH subcellular location Targeted to peroxisomes via the endoplasmic reticulum.
GPT1_ARATH tissue specificity Expressed in seeds, flowers, rosette leaves, and roots, with highest levels found in stamens. Found in the root cap, in guard cells and in mesophyll cells.
