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]
GCLC (Glutamate-Cysteine Ligase Catalytic Subunit) is a Protein Coding gene. Diseases associated with GCLC include Gamma-Glutamylcysteine Synthetase Deficiency, Hemolytic Anemia Due To and Myocardial Infarction. Among its related pathways are One carbon pool by folate and Photodynamic therapy-induced NFE2L2 (NRF2) survival signaling. Gene Ontology (GO) annotations related to this gene include protein heterodimerization activity and coenzyme binding.
