Methylmalonic Aciduria (Cobalamin Deficiency) CblB Type Proteins (MMAB)

Human Methylmalonic Aciduria (Cobalamin Deficiency) CblB Type (MMAB) interaction partners

1. analysis of how molecular chaperones interact with ATR in methylmalonic aciduria cblB type

2. MMAB might be a target and potential biomarker of hepatotoxicity in EFV-induced liver toxicity

3. These findings suggest that rs11066782 in KCTD10, rs11613718 in KCTD10 and rs11067233 in MMAB may contribute to the susceptibility of coronary heart disease by altering plasma HDL-C levels in Han Chinese.

4. MMAB mutations, including one novel nonsense mutation (c.12 C>A [p.C4X]), were identified in all members of the cblB cohort.

5. Pathogenicity of the human truncation mutant results from its inability to sequester AdoCbl for direct transfer to methylmalonyl-CoA mutase (show MUT Proteins), resulting in holoenzyme formation.

6. c.584G>A, c.349-1G>C, and c.290G>A mutations affect the splicing process of ATR.

7. These data suggest MMAB is the most likely gene influencing high-density lipoprotein-cholesterol levels at MMAB-MVK (show MVK Proteins) locus.

8. Characterization of ligand-binding by MMAB provides insight into the mechanism of cobalamin adenosylation and the effect of patient mutations in the inherited disorder

9. report the identification of ATR cDNA as well as the corresponding gene; ATR expression is altered in cell lines derived from cblB methylmalonyl aciduria patients; propose that inborn errors in the ATR gene identified here result in methylmalonyl aciduria

10. Results describe two common polymorphic variants of ATP:cob(I)alamin adenosyltransferase that are found in normal individuals, and their interactions with methionine synthase reductase (show MTRR Proteins).

Cow (Bovine) Methylmalonic Aciduria (Cobalamin Deficiency) CblB Type (MMAB) interaction partners

1. report the isolation of an ATR cDNA, from a bovine liver library, by complementation of an ATR-deficient Salmonella mutant.

Mouse (Murine) Methylmalonic Aciduria (Cobalamin Deficiency) CblB Type (MMAB) interaction partners

1. The mouse methylmalonic aciduria- related genes, Mmaa (show MMAA Proteins), Mmab, and Mut (show MUT Proteins) may have specialized functions depending on the tissue or cell type.
