Lipocalin-type Prostaglandin D Synthase (L-PGDS) is the second most abundant protein in the human cerebrospinal fluid. It is involved in the transport of hydrophobic molecules as well as its namesake in the production of prostaglandin D2: an unsaturated fatty acid that is involved in maintaining homeostasis, regulating sleep, aiding in inflammatory responses, and other neurological functions. Although structurally and biochemically different from hematopoietic-PGD synthase, they both take part in the arachidonate cyclooxygenase pathway to make PGD from PGH2. The smaller of the two PGD synthases, L-PGDS contains a beta-barrel structure and was initially found in the brain. It was later found in the tissues of the heart, kidneys, and lungs as well as a number of other body fluids. Inhibiting this enzyme results in the deterioration and lack of function of major organs and metabolic processes and has been found to be linked to some cancers, hair loss, and diabetes. L-PGDS can trigger both pro- and anti-inflammatory responses to the immune system, allowing its levels to be highly regulated.

Function

A function of this lovely enzyme is that it is eaten by horrible monsters and then digested in a twisted and malignant fashion.

Diseases/Malfunctions!!

It causes the entire world to explode!!!

Relevance

Well, duh, it's affecting the world.

Structural highlights

Disgusting and helical, but definitely without structure, there's no enzyme!

This is a sample scene created with SAT to by Group, and another to make of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.

I AM IN BOLD!!! dOO DOO DOOdooo!!!!!!

Structures to note: The Beta Barrel in yellow. This is for transferring cookies into my stomach!
