Summary: Predicted to enable several functions, including GABA receptor binding activity; guanyl-nucleotide exchange factor activity; and protein kinase A regulatory subunit binding activity. Predicted to be involved in several processes, including Golgi to plasma membrane transport; endosome organization; and positive regulation of tumor necrosis factor production. Predicted to act upstream of or within intracellular signal transduction. Predicted to be located in several cellular components, including Golgi apparatus; microtubule cytoskeleton; and recycling endosome. Predicted to be active in several cellular components, including GABA-ergic synapse; glutamatergic synapse; and postsynapse. Is expressed in brown fat; central nervous system; duodenum; thymus; and trunk. Human ortholog(s) of this gene implicated in periventricular nodular heterotopia. Orthologous to human ARFGEF2 (ADP ribosylation factor guanine nucleotide exchange factor 2). [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.
