| Primary Identifier | IPR036392 | Type | Homologous_superfamily |
| Short Name | PLAT/LH2_dom_sf |
| description | This entry represents a domain superfamily found in a variety of membrane or lipid associated proteins. It is known as the PLAT (Polycystin-1, Lipoxygenase, Alpha-Toxin) domain or LH2 (Lipoxygenase homology) domain, is found in a variety of membrane or lipid associated proteins. Structurally, this domain forms a β-sandwich composed of two sheets of four strands each [, , ]. The most highly conserved regions coincide with the β-strands, with most of the highly conserved residues being buried within the protein. An exception to this is a surface lysine or arginine that occurs on the surface of the fifth β-strand of the eukaryotic domains. In pancreatic lipase, the lysine in this position forms a salt bridge with the procolipase protein. The conservation of a charged surface residue may indicate the location of a conserved ligand-binding site. It is thought that this domain may mediate membrane attachment via other protein binding partners. |
