    Summary
    Predicted to enable signaling receptor binding activity. Predicted to be involved in T cell receptor signaling pathway and regulation of cytokine production. Predicted to be located in membrane. Predicted to be active in external side of plasma membrane. Is expressed in central nervous system; genitourinary system; and heart valve. Orthologous to human BTN1A1 (butyrophilin subfamily 1 member A1). [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.
