Comments

Comment type	Description
Disruption Phenotype	No visible phenotype under normal growth conditions, but mutant plants exhibit an impaired response to phosphate deficiency during root development. {ECO:0000269\|PubMed:20053799}.
Domain	The nitrogen atoms of the two glycine residues in the GGXR motif define the oxyanion hole, and stabilize the oxyanion that forms during the nucleophilic attack by the catalytic serine during substrate cleavage. {ECO:0000250}.
Function	Possesses non-specific lipolytic acyl hydrolase (LAH) activity. Catalyzes the hydrolysis of the neutral lipids monogalactosyldiacylglycerol (MGDG), digalactosyldiacylglycerol (DGDG) and phosphatidylglycerol (PG), and less efficiently the polar lipids phosphatidylcholine (PC) and phosphatidylinositol (PI), but not the storage lipid triacylglycerol (TAG). May play a role in root development. {ECO:0000269\|PubMed:20053799}.
Induction	By abscisic acid (ABA) or phosphate deficiency in roots. {ECO:0000269\|PubMed:20053799}.
Similarity	Belongs to the patatin family. {ECO:0000305}.
Similarity	Contains 1 patatin domain. {ECO:0000305}.
Subcellular Location	Cytoplasm {ECO:0000269\|PubMed:12226489}.
Tissue Specificity	Expressed specifically in the stigma, ovary and funiculus of the ovary. {ECO:0000269\|PubMed:12226489, ECO:0000269\|PubMed:20053799}.
