Summary: This gene encodes a protein that has been shown to function as a guanine nucleotide release factor in mouse and to regulate the expression and function of the Nav1.5 cardiac sodium channel in human. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2010]
Expression: Broad expression in testis (RPKM 13.3), endometrium (RPKM 7.1) and 24 other tissues See more

What's a GeneRIF?

The MOG1 domain required for the interaction with Nav1.5 to the region spanning amino acids 146-174, and a refined deletion analysis further narrowed this domain to amino acids146-155.
Title: Mechanistic insights into the interaction of the MOG1 protein with the cardiac sodium channel Na(v)1.5 clarify the molecular basis of Brugada syndrome.
Suggest that p.E61X_RANGRF is a rare genetic variation with an uncertain role in Brugada Syndrome.
Title: Brugada syndrome and p.E61X_RANGRF.
Compound mutation of CACNA2D1 and RANGRF genes were found. To the best of our knowledge, this is the first comprehensive description of the concurrence of these two mutations and histiocytoid cardiomyopathy.
Title: The perfect storm? Histiocytoid cardiomyopathy and compound CACNA2D1 and RANGRF mutation in a baby.
Results suggest that dominant-negative mutations in MOG1 can impair the trafficking of Na(v)1.5 to the membrane, leading to I(Na) reduction and clinical manifestation of Brugada syndrome.
Title: MOG1: a new susceptibility gene for Brugada syndrome.
Our screening of Nav1.5 cofactor MOG1 uncovered a novel nonsense variant that appeared to be present at a higher frequency among these patients with atrial fibrillation and Brugada syndrome than control subjects.
Title: A novel nonsense variant in Nav1.5 cofactor MOG1 eliminates its sodium current increasing effect and may increase the risk of arrhythmias.
in cardiomyocytes, MOG1 is mostly localized in the cell membrane and co-localized with Nav1.5, indicating that MOG1 is a critical regulator of sodium channel function in the heart
Title: Identification of a new co-factor, MOG1, required for the full function of cardiac sodium channel Nav 1.5.

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.
