Template:PBB Controls

Leukotriene C4 synthase, also known as LTC4S, is a human gene.^[5]

The protein encoded by this gene, LTC4S (or glutathione S-transferase II) is an enzyme which converts leukotriene A4 and glutathione to create leukotriene C4. This is a member of MAPEG family of transmembrane proteins.

A trimer of Leukotriene C4 synthase is localized on the outer nuclear membrane and endoplasmic reticulum where it forms a complex with 5-Lipoxygenase activating protein. This protein is remotely related to microsomal glutathione S-transferase.
