Summary: Enables cAMP binding activity and guanyl-nucleotide exchange factor activity. Involved in several processes, including nervous system development; positive regulation of neuronal action potential; and regulation of protein localization. Located in several cellular components, including basolateral plasma membrane; brush border; and distal axon. Part of protein-containing complex. Is active in glutamatergic synapse; postsynaptic density; and presynapse. 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.
