Summary: Predicted to enable GDP binding activity; GTP binding activity; and GTPase activity. 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. Predicted to be located in cell-cell junction; cytosol; and lipid droplet. Predicted to be active in plasma membrane. Is expressed in brain and cerebral cortex. Orthologous to human RAP1B (RAP1B, member of RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]

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.
