MGI Phenotype FUNCTION: The protein encoded by this gene is an enzyme that catalyzes the synthesis of leukotriene C4 by combining leukotriene A4 with reduced glutathione. The encoded protein is found in the outer nuclear membrane and in the peripheral endoplasmic reticulum. Leukotrienes have been implicated as mediators of anaphylaxis and inflammatory conditions such as bronchial asthma in humans. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]
PHENOTYPE: Mice homozygous for disruptions in this gene display abnormal inflammatory and hypersensitivity reactions but are otherwise normal. [provided by MGI curators]
