| Pathway: | |
One-carbon metabolism; tetrahydrofolate interconversion. |
| Subunit: | |
Homodimer. {ECO:0000269|PubMed:10828945}. |
| Subcellular location: | |
Cytoplasm. |
| Tissue specificity: | |
Ubiquitous. |
| Domain: | |
This trifunctional enzyme consists of two major domains: an N- terminal part containing the methylene-THF dehydrogenase and cyclohydrolase activities and a larger C-terminal part containing formyl-THF synthetase activity. |
| Disease: | |
Neural tube defects, folate-sensitive (NTDFS) [MIM:601634]: The most common NTDs are open spina bifida (myelomeningocele) and anencephaly. {ECO:0000269|PubMed:12384833, ECO:0000269|PubMed:16552426, ECO:0000269|PubMed:9611072}. Note=Disease susceptibility is associated with variants affecting the gene represented in this entry. |
| Disease: | |
Colorectal cancer (CRC) [MIM:114500]: A complex disease characterized by malignant lesions arising from the inner wall of the large intestine (the colon) and the rectum. Genetic alterations are often associated with progression from premalignant lesion (adenoma) to invasive adenocarcinoma. Risk factors for cancer of the colon and rectum include colon polyps, long-standing ulcerative colitis, and genetic family history. {ECO:0000269|PubMed:17000706}. Note=Disease susceptibility may be associated with variants affecting the gene represented in this entry. Susceptibility to colorectal cancer may be associated with the missense variant p.Arg134Lys, which has been observed in about 16% of the human population. The sequence shown in this entry represents the minor allele, as it is reported in the reference genome. {ECO:0000269|PubMed:17000706}. |
| Disease: | |
Combined immunodeficiency and megaloblastic anemia with or without hyperhomocysteinemia (CIMAH) [MIM:617780]: An autosomal recessive disorder due to an inborn error of folate metabolism. Variable clinical manifestations include hemolytic uremic syndrome, macrocytosis, epilepsy, hearing loss, retinopathy, mild mental retardation, and lymphopenia. {ECO:0000269|PubMed:21813566, ECO:0000269|PubMed:25633902, ECO:0000269|PubMed:27707659}. Note=The disease is caused by variants affecting the gene represented in this entry. |
