Summary: Enables G protein activity. Involved in modification of postsynaptic structure. Acts upstream of or within several processes, including negative regulation of regulated secretory pathway; positive regulation of ERK1 and ERK2 cascade; and small GTPase-mediated signal transduction. Is active in glutamatergic synapse. Is expressed in brain and eye. Human ortholog(s) of this gene implicated in thrombocytopenia. Orthologous to several human genes including RAP1B (RAP1B, member of RAS oncogene family). [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.
