    Summary
    Predicted to enable several functions, including GTPase activity; guanyl ribonucleotide binding activity; and myosin V binding activity. Involved in anterograde axonal protein transport; regulation of exocytosis; and synaptic vesicle endocytosis. Located in apical plasma membrane and zymogen granule membrane. Is active in synaptic vesicle membrane. Orthologous to human RAB27B (RAB27B, member 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.
