About This Section

Entrez Gene summary for MTRR:
Methionine is an essential amino acid required for protein synthesis and one-carbon metabolism. Its synthesis is
catalyzed by the enzyme methionine synthase. Methionine synthase eventually becomes inactive due to the oxidation of
its cob(I)alamin cofactor. The protein encoded by this gene regenerates a functional methionine synthase via reductive
methylation. It is a member of the ferredoxin-NADP(+) reductase (FNR) family of electron transferases. Patients of the
cbl-E complementation group of disorders of folate/cobalamin metabolism are defective in reductive activation of
methionine synthase. Alternative splicing of this gene results in multiple transcript variants encoding distinct
isoforms. (provided by RefSeq, Jul 2008)

UniProtKB/Swiss-Prot: MTRR_HUMAN, Q9UBK8
Function: Involved in the reductive regeneration of cob(I)alamin cofactor required for the maintenance of methionine
synthase in a functional state

  • Defects in MTRR are the cause of methylcobalamin deficiency type E (cblE) [MIM:236270]; also known as vitamin
  • B12-responsive homocystinuria or homocystinuria-megaloblastic anemia complementation type E. Patients who are
    defective in reductive activation of methionine synthase exhibit megaloblastic anemia, developmental delay,
    hypomethioninemia, and hyperhomocysteinemia, a risk factor in cardiovascular disease and neural tube defects. It is an
    autosomal recessive disease
  • Defects in MTRR may be a cause of susceptibility to folate-sensitive neural tube defects (FS-NTD)
  • [MIM:601634]. The most common NTDs are open spina bifida (myelomeningocele) and anencephaly. Genetic defects in MTRR
    may affect the risk of spina bifida via the maternal rather than the embryonic genotype
