BHMT betaine--homocysteine S-methyltransferase [Homo sapiens (human)] - Gene

Summary

Official Symbol: BHMTprovided by HGNC
Official Full Name: betaine--homocysteine S-methyltransferaseprovided by HGNC
Primary source: HGNC:HGNC:1047
See related: Ensembl:ENSG00000145692 MIM:602888; AllianceGenome:HGNC:1047
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: BHMT1; HEL-S-61p
Summary: This gene encodes a cytosolic enzyme that catalyzes the conversion of betaine and homocysteine to dimethylglycine and methionine, respectively. Defects in this gene could lead to hyperhomocyst(e)inemia, but such a defect has not yet been observed. [provided by RefSeq, Jul 2008]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
