Summaries for CTH Gene

Entrez Gene Summary for CTH Gene

  • This gene encodes a cytoplasmic enzyme in the trans-sulfuration pathway that converts cystathione derived from methionine into cysteine. Glutathione synthesis in the liver is dependent upon the availability of cysteine. Mutations in this gene cause cystathioninuria. Alternative splicing of this gene results in three transcript variants encoding different isoforms. [provided by RefSeq, Jun 2010]

GeneCards Summary for CTH Gene

CTH (Cystathionine Gamma-Lyase) is a Protein Coding gene. Diseases associated with CTH include Cystathioninuria and Methionine Adenosyltransferase I/Iii Deficiency. Among its related pathways are One carbon pool by folate and Viral mRNA Translation. Gene Ontology (GO) annotations related to this gene include calmodulin binding and carbon-sulfur lyase activity.

UniProtKB/Swiss-Prot for CTH Gene

  • Catalyzes the last step in the trans-sulfuration pathway from methionine to cysteine. Has broad substrate specificity. Converts cystathionine to cysteine, ammonia and 2-oxobutanoate. Converts two cysteine molecules to lanthionine and hydrogen sulfide. Can also accept homocysteine as substrate. Specificity depends on the levels of the endogenous substrates. Generates the endogenous signaling molecule hydrogen sulfide (H2S), and so contributes to the regulation of blood pressure. Acts as a cysteine-protein sulfhydrase by mediating sulfhydration of target proteins: sulfhydration consists of converting -SH groups into -SSH on specific cysteine residues of target proteins such as GAPDH, PTPN1 and NF-kappa-B subunit RELA, thereby regulating their function.
