Gene Gene information from NCBI Gene database.
Entrez ID 4552
Gene name 5-methyltetrahydrofolate-homocysteine methyltransferase reductase
Gene symbol MTRR
Synonyms (NCBI Gene)
MSRcblE
Chromosome 5
Chromosome location 5p15.31
Summary This gene encodes a member of the ferredoxin-NADP(+) reductase (FNR) family of electron transferases. This protein functions in the synthesis of methionine by regenerating methionine synthase to a functional state. Because methionine synthesis requires me
