UniProtKB - Q9XIE6 (ALA3_ARATH)

Protein

Phospholipid-transporting ATPase 3

Gene

ALA3

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. Required for secretory processes during plant development. Requires an interaction with an ALIS protein for activity. Has activity with phosphatidylserine, phosphatidylcholine and phosphatidylethanolamine, but not with lysolipid (PubMed:18344284, PubMed:19566596, PubMed:20053675). Modifies endomembranes in multiple cell types, enabling structural changes, or signaling functions that are critical for normal development and adaptation to varied growth environments (PubMed:23667493).4 Publications

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

Disruption phenotypei

Impaired growth of roots and shoots (PubMed:18344284, PubMed:23667493). Roots devoided of the characteristic trans-Golgi proliferation of slime vesicles containing polysaccharides and enzymes for secretion (PubMed:18344284). Aberrant trichome expansion, reduced primary root growth and longer root hairs (PubMed:19566596). Impaired pollen growth (PubMed:19566596, PubMed:23667493). Impaired ovule development (PubMed:23667493). Reduced adaptability to temperature stresses (PubMed:23667493).3 Publications

Expressioni

Tissue specificityi

Expressed in petals and sepals, but not in reproductive tissues. In siliques, detected in the upper part of the seed pod and in the area between the seed pod and the stem, but not in developing seeds. Strong expression in vascular shoot tissues and in stomatal guard cells of young rosettes leaves. In roots, expressed in cells surrounding the xylem and in central and peripheral columella cells. Detected in developing and mature trichomes, roots, pollen and growing pollen tubes.2 Publications
