Protein

Phospholipid-transporting ATPase 2

Gene

ALA2

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

Functioni

Involved in transport of phospholipids. Contributes to transmembrane flipping of lipids. Requires an interaction with a protein of the ALIS family for activity. Specific for phosphatidylserine and has no activity with lysolipid, phosphatidylcholine or phosphatidylethanolamine.1 Publication

Miscellaneous

The intracellular targeting signals and lipid specificity determinants reside in the catalytic ALA subunit.1 Publication

Catalytic activityi

ATP + H2O + phospholipid(Side 1) = ADP + phosphate + phospholipid(Side 2).1 Publication
