Summary: Enables methylmalonyl-CoA mutase activity. Involved in succinyl-CoA biosynthetic process. Acts upstream of or within post-embryonic development. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; lung; nervous system; and trophectoderm. Used to study methylmalonic aciduria due to methylmalonyl-CoA mutase deficiency. Human ortholog(s) of this gene implicated in methylmalonic aciduria due to methylmalonyl-CoA mutase deficiency. Orthologous to human MMUT (methylmalonyl-CoA mutase). [provided by Alliance of Genome Resources, Dec 2024]

We confirmed significant NH4(+) accumulation in culture media of Mut(-/-) aggregates, suggesting that intracellular NH4(+) concentrations might even be higher, gave first clues on the mechanisms leading to NH4(+) accumulation in Mut(-/-) brain cells, and showed the involvement of neuroinflammatory processes in the neuropathophysiology of Methylmalonic aciduria .
Title: New in vitro model derived from brain-specific Mut-/- mice confirms cerebral ammonium accumulation in methylmalonic aciduria.
On a high protein diet, mutant mice display disease exacerbation, including elevated blood ammonia, and catastrophic weight loss, which, in Mut(ki/ki) mice, is rescued by hydroxocobalamin treatment. This study expands knowledge of MMAuria, introduces the discovery of new biomarkers, and constitutes the first in vivo proof of principle of cobalamin treatment in mut-type MMAuria.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
