Summaries for GCLM Gene

Entrez Gene Summary for GCLM Gene

  • 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. Gamma glutamylcysteine synthetase deficiency has been implicated in some forms of hemolytic anemia. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Apr 2015]

GeneCards Summary for GCLM Gene

GCLM (Glutamate-Cysteine Ligase Modifier Subunit) is a Protein Coding gene. Diseases associated with GCLM include Myocardial Infarction and Ancylostomiasis. Among its related pathways are Photodynamic therapy-induced NFE2L2 (NRF2) survival signaling and Viral mRNA Translation. GO annotations related to this gene include protein heterodimerization activity and glutamate-cysteine ligase activity.
