Summary: Contributes to guanyl-nucleotide exchange factor activity. Involved in several processes, including hippocampus development; positive regulation of axon extension; and response to glucose. Located in axon. Part of eukaryotic translation initiation factor 2B complex. Is active in endoplasmic reticulum; glycinergic synapse; and postsynapse.

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.
