Previous GeneCards Identifiers for RANGRF Gene
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]

RANGRF (RAN Guanine Nucleotide Release Factor) is a Protein Coding gene. Diseases associated with RANGRF include Brugada Syndrome and Sick Sinus Syndrome. Among its related pathways are Phase 0 - rapid depolarisation and Cardiac conduction. Gene Ontology (GO) annotations related to this gene include guanyl-nucleotide exchange factor activity and protein transporter activity.
UniProtKB/Swiss-Prot Summary for RANGRF Gene
May regulate the intracellular trafficking of RAN (PubMed:11290418). Promotes guanine nucleotide release from RAN and inhibits binding of new GTP by preventing the binding of the RAN guanine nucleotide exchange factor RCC1 (PubMed:29040603). Regulates the levels of GTP-bound RAN in the nucleus, and thereby plays a role in the regulation of RAN-dependent mitotic spindle dynamics (PubMed:29040603). Enhances the expression of SCN5A at the cell membrane in cardiomyocytes (PubMed:18184654, PubMed:23420830, PubMed:21621375).
