PLAT/LH2 domain of pancreatic triglyceride lipase. Lipases hydrolyze phospholipids and triglycerides to generate fatty acids for energy production or for storage and to release inositol phosphates that act as second messengers. The central role of triglyceride lipases is in energy production. The proposed function of PLAT/LH2 domains is to mediate interaction with lipids or membrane bound proteins.

Pancreatic lipase-like enzymes. Lipases are esterases that can hydrolyze long-chain acyl-triglycerides into di- and monoglycerides, glycerol, and free fatty acids at a water/lipid interface. A typical feature of lipases is "interfacial activation," the process of becoming active at the lipid/water interface, although several examples of lipases have been identified that do not undergo interfacial activation . The active site of a lipase contains a catalytic triad consisting of Ser - His - Asp/Glu, but unlike most serine proteases, the active site is buried inside the structure. A "lid" or "flap" covers the active site, making it inaccessible to solvent and substrates. The lid opens during the process of interfacial activation, allowing the lipid substrate access to the active site.

lipoprotein lipase; Members of this protein family are lipoprotein lipase (EC 3.1.1.34), a eukaryotic triacylglycerol lipase active in plasma and similar to pancreatic and hepatic triacylglycerol lipases (EC 3.1.1.3). It is also called clearing factor. It cleaves chylomicron and VLDL triacylglycerols; it also has phospholipase A-1 activity.

PLAT/LH2 domain; This domain is found in a variety of membrane or lipid associated proteins. It is called the PLAT (Polycystin-1, Lipoxygenase, Alpha-Toxin) domain or LH2 (Lipoxygenase homology) domain. The known structure of pancreatic lipase shows this domain binds to procolipase pfam01114, which mediates membrane association. So it appears possible that this domain mediates membrane attachment via other protein binding partners. The structure of this domain is known for many members of the family and is composed of a beta sandwich.

PLAT/ LH2 domain present in connection with a lipase domain. This family contains two major subgroups, the lipoprotein lipase (LPL) and the pancreatic triglyceride lipase. LPL is a key enzyme in catabolism of plasma lipoprotein triglycerides (TGs). The central role of triglyceride lipases is in energy production. In general, PLAT/LH2 domain's proposed function is to mediate interaction with lipids or membrane bound proteins.

PLAT (Polycystin-1, Lipoxygenase, Alpha-Toxin) domain or LH2 (Lipoxygenase homology 2) domain. It consists of an eight stranded beta-barrel. The domain can be found in various domain architectures, in case of lipoxygenases, alpha toxin, lipases and polycystin, but also as a single domain or as repeats.The putative function of this domain is to facilitate access to sequestered membrane or micelle bound substrates.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
