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 methyl-group transfer by a folate donor, activity of the encoded enzyme is important for folate metabolism and cellular methyla... See more...

Entrez Gene Summary for MTRR Gene

  • 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 methyl-group transfer by a folate donor, activity of the encoded enzyme is important for folate metabolism and cellular methylation. Mutations in this gene can cause homocystinuria-megaloblastic anemia, cbl E type. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Dec 2015]

GeneCards Summary for MTRR Gene

MTRR (5-Methyltetrahydrofolate-Homocysteine Methyltransferase Reductase) is a Protein Coding gene. Diseases associated with MTRR include Homocystinuria-Megaloblastic Anemia, Cble Complementation Type and Neural Tube Defects, Folate-Sensitive. Among its related pathways are Folate Metabolism and Cytochrome P450 - arranged by substrate type. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity and flavin adenine dinucleotide binding. An important paralog of this gene is POR.

UniProtKB/Swiss-Prot Summary for MTRR Gene

  • Key enzyme in methionine and folate homeostasis responsible for the reactivation of methionine synthase (MTR/MS) activity by catalyzing the reductive methylation of MTR-bound cob(II)alamin (PubMed:17892308). Cobalamin (vitamin B12) forms a complex with MTR to serve as an intermediary in methyl transfer reactions that cycles between MTR-bound methylcob(III)alamin and MTR bound-cob(I)alamin forms, and occasional oxidative escape of the cob(I)alamin intermediate during the catalytic cycle leads to the inactive cob(II)alamin species (Probable). The processing of cobalamin in the cytosol occurs in a multiprotein complex composed of at least MMACHC, MMADHC, MTRR and MTR which may contribute to shuttle safely and efficiently cobalamin towards MTR in order to produce methionine (PubMed:27771510). Also necessary for the utilization of methyl groups from the folate cycle, thereby affecting transgenerational epigenetic inheritance (By similarity). Also acts as a molecular chaperone for methionine synthase by stabilizing apoMTR and incorporating methylcob(III)alamin into apoMTR to form the holoenzyme (PubMed:16769880). Also serves as an aquacobalamin reductase by reducing aquacobalamin to cob(II)alamin in the presence of NADPH; this reduction leads to stimulation of the conversion of apoMTR and aquacobalamin to MTR holoenzyme (PubMed:16769880).

MTRR_HUMAN
  • Homocystinuria-megaloblastic anemia, cblE complementation type (HMAE) [MIM:236270]: An autosomal recessive inborn error of metabolism resulting from defects in the cobalamin-dependent pathway that converts homocysteine to methionine. It causes delayed psychomotor development, megaloblastic anemia, homocystinuria, and hypomethioninemia. Cells from patients with HMAE fail to incorporate methyltetrahydrofolate into methionine in whole cells, but cell extracts show normal methionine synthase activity in the presence of a reducing agent. {ECO:0000269 PubMed:10484769, ECO:0000269 PubMed:9501215}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Neural tube defects, folate-sensitive (NTDFS) [MIM:601634]: The most common NTDs are open spina bifida (myelomeningocele) and anencephaly. {ECO:0000269 PubMed:10444342, ECO:0000269 PubMed:12375236}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
