Protein

Mitochondrial phosphate carrier protein 1, mitochondrial

Gene

MPT1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Transport of phosphate groups from the cytosol to the mitochondrial matrix. Mediates salt stress tolerance through an ATP-dependent pathway and via modulation of the gibberellin metabolism.1 Publication

Miscellaneous

Plants overexpressing MPT1/PHT3;3 display increased sensitivity to salt stress.1 Publication
