    Summary
    Enables cannabinoid receptor activity. Involved in several processes, including negative regulation of GABAergic synaptic transmission; negative regulation of mast cell activation; and negative regulation of nitric-oxide synthase activity. Located in dendrite and neuronal cell body. Is extrinsic component of cytoplasmic side of plasma membrane. Is active in postsynaptic membrane. Used to study Huntington's disease; arthritis; and sciatic neuropathy. Biomarker of pancreatitis. Orthologous to human CNR2 (cannabinoid receptor 2).

    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.
