Summaries for BHMT2 Gene

Entrez Gene Summary for BHMT2 Gene

  • Homocysteine is a sulfur-containing amino acid that plays a crucial role in methylation reactions. Transfer of the methyl group from betaine to homocysteine creates methionine, which donates the methyl group to methylate DNA, proteins, lipids, and other intracellular metabolites. The protein encoded by this gene is one of two methyl transferases that can catalyze the transfer of the methyl group from betaine to homocysteine. Anomalies in homocysteine metabolism have been implicated in disorders ranging from vascular disease to neural tube birth defects such as spina bifida. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2010]

GeneCards Summary for BHMT2 Gene

BHMT2 (Betaine--Homocysteine S-Methyltransferase 2) is a Protein Coding gene. Among its related pathways are Metabolism and One carbon pool by folate. GO annotations related to this gene include S-adenosylmethionine-homocysteine S-methyltransferase activity and S-methylmethionine-homocysteine S-methyltransferase activity. An important paralog of this gene is BHMT.
