Summary: Predicted to enable guanyl-nucleotide exchange factor activity. Involved in postsynaptic modulation of chemical synaptic transmission. Acts upstream of or within long-term synaptic potentiation and regulation of NMDA receptor activity. Is active in glutamatergic synapse. Is expressed in brain; hypothalamus mantle layer; medulla oblongata basal plate mantle layer; and pons mantle layer. Orthologous to human RASGRF2 (Ras protein specific guanine nucleotide releasing 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.
