In molecular biology the PLAT domain is a protein domain that is found in a variety of membrane or lipid associated proteins. It is called the PLAT (Polycystin-1, Lipoxygenase, Alpha-Toxin) domain[2] or LH2 (Lipoxygenase homology) domain.[3] The known structure of pancreatic lipase shows this domain binds to procolipase Pfam PF01114, which mediates membrane association.

This domain forms a beta-sandwich composed of two β-sheets of four β-strands each.[2][4][5]
