    Summary
    Predicted to enable IgG binding activity and beta-2-microglobulin binding activity. Predicted to be involved in immune response. Predicted to be located in endosome membrane and plasma membrane. Predicted to be active in external side of plasma membrane and extracellular space. Is expressed in several structures, including genitourinary system; heart valve; intestine; sensory organ; and skeleton. Orthologous to human FCGRT (Fc gamma receptor and transporter).

    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.
