| Function | Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity). {ECO:0000250}. |
| Subcellular Location | Cytoplasm. |
| Tissue Specificity | Widely expressed. Expressed at the highest levels in pancreas, heart, brain, skeletal muscle and placenta. Expressed at lower levels in lung, liver and kidney. |
| Top Pathways | Cysteine and methionine metabolism, Selenocompound metabolism, Biosynthesis of amino acids, One carbon pool by folate |
