Entrez Gene summary for LTC4S:

The MAPEG (Membrane Associated Proteins in Eicosanoid and Glutathione metabolism) family includes a number of human

proteins, several of which are involved the production of leukotrienes. This gene encodes an enzyme that catalyzes the

first step in the biosynthesis of cysteinyl leukotrienes, potent biological compounds derived from arachidonic acid.

Leukotrienes have been implicated as mediators of anaphylaxis and inflammatory conditions such as human bronchial

asthma. This protein localizes to the nuclear envelope and adjacent endoplasmic reticulum. (provided by RefSeq, Jul

2008)

UniProtKB/Swiss-Prot: LTC4S_HUMAN, Q16873

Function: Catalyzes the conjugation of leukotriene A4 with reduced glutathione to form leukotriene C4

Defects in LTC4S are the cause of leukotriene C4 synthase deficiency (LTC4 synthase deficiency) [MIM:246530].

LTC4 synthase deficiency is a fatal neurometabolic developmental disorder. It is associated with muscular hypotonia,

psychomotor retardation, failure to thrive, and microcephaly
