Summary: Enables several functions, including cAMP binding activity; guanyl-nucleotide exchange factor activity; and small GTPase binding activity. Involved in positive regulation of insulin secretion and regulation of synaptic vesicle cycle. Acts upstream of or within with a positive effect on hormone secretion. Acts upstream of or within adenylate cyclase-activating G protein-coupled receptor signaling pathway; regulation of exocytosis; and secretion by cell. Is active in cytosol and hippocampal mossy fiber to CA3 synapse. Is expressed in several structures, including adrenal gland; ganglia; heart; lung; and metanephros. Human ortholog(s) of this gene implicated in autistic disorder. Orthologous to human RAPGEF4 (Rap guanine nucleotide exchange factor 4). [provided by Alliance of Genome Resources, Dec 2024]

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.
