Sucrose/H+ symporter, plant (IPR005989)

Short name: Suc_symporter_pln

Overlapping homologous superfamilies

Family relationships



These sucrose/proton symporters, found in plants, are from the Glycoside-Pentoside-Hexuronide (GPH)/cation symporter family. These proteins are predicted to have 12 transmembrane domains. Members may export sucrose (e.g. SUT1, SUT4) from green parts to the phloem for long-distance transport or import sucrose (e.g SUT2) to sucrose sinks such as the tap root of the carrot [PMID: 9847123].
