RT "Trk1 and Trk2 define the major K(+) transport system in fission yeast.";
RL J. Bacteriol. 182:394-399(2000).
CC -!- FUNCTION: Together with TRK2, defines the major, high-affinity
CC potassium influx transport system. Involved in maintenance of the
CC proper sodium/potassium ratio in the cell and in regulating the plasma
CC membrane potential. {ECO:0000269|PubMed:10629185}.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
CC -!- SIMILARITY: Belongs to the TrkH potassium transport family.
CC {ECO:0000305}.
