  Domain Name: Pat17_PNPLA8_PNPLA9_
Patatin-like phospholipase; includes PNPLA8, PNPLA9, and Pat17. Patatin is a storage protein of the potato tuber that shows Phospholipase A2 activity (PLA2; EC 3.1.1.4). Patatin catalyzes the nonspecific hydrolysis of phospholipids, glycolipids, sulfolipids, and mono- and diacylglycerols, thereby showing lipid acyl hydrolase activity. The active site includes an oxyanion hole with a conserved GGxR motif; it is found in almost all the members of this family. The catalytic dyad is formed by a serine and an aspartate. Patatin belongs to the alpha-beta hydrolase family which is identified by a characteristic nucleophile elbow with a consensus sequence of Sm-X-Nu-Sm (Sm = small residue, X = any residue and Nu = nucleophile). Members of this family have been found also in vertebrates. This family includes subfamily of PNPLA8 (iPLA2-gamma) and PNPLA9 (iPLA2-beta) like phospholipases from human as well as the Pat17 isozyme from Solanum cardiophyllum.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
