    Summary
    Predicted to enable GTPase activator activity and guanyl-nucleotide exchange factor activity. Predicted to be involved in G protein-coupled receptor signaling pathway and regulation of signaling. Predicted to act upstream of or within adult locomotory behavior; dendrite morphogenesis; and phosphatidylinositol 3-kinase/protein kinase B signal transduction. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in Klatskin's tumor and cholangiocarcinoma. Orthologous to human PREX2 (phosphatidylinositol-3,4,5-trisphosphate dependent Rac 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.
