FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Glutamate-cysteine ligase, also known as gamma-glutamylcysteine synthetase is the first rate-limiting enzyme of glutathione synthesis. The enzyme consists of two subunits, a heavy catalytic subunit and a light regulatory subunit. This locus encodes the catalytic subunit, while the regulatory subunit is derived from a different gene located on chromosome 1p22-p21. Mutations at this locus have been associated with hemolytic anemia due to deficiency of gamma-glutamylcysteine synthetase and susceptibility to myocardial infarction.[provided by RefSeq, Oct 2010]
PHENOTYPE: Homozygous mutant mice are embryonic lethal. One model shows lethality before E13 while another shows lethality between E7.5-E8.5. In this second model, embryos are arrested at the egg cylinder stage, fail to gastrulate, do not form mesoderm, and exhibitincreased apoptosis. [provided by MGI curators]
