OverviewNCBI Gene
The protein encoded by this gene is a guanine nucleotide exchange factor (GEF) similar to the Saccharomyces cerevisiae CDC25 gene product. Functional analysis has demonstrated that this protein stimulates the dissociation of GDP from RAS protein. The studies of the similar gene in mouse suggested that the Ras-GEF activity of this protein in brain can be activated by Ca2+ influx, muscarinic receptors, and G protein beta-gamma subunit. Mouse studies also indicated that the Ras-GEF signaling pathway mediated by this protein may be important for long-term memory. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Mar 2009]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads RASGRF1 as an antibody target. Whether an autoantibody or antibody against RASGRF1 could matter depends on whether native RASGRF1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
RASGRF1 is annotated at the cell surface, where native RASGRF1 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label RASGRF1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
