    Summary
    Predicted to enable several functions, including complement receptor activity; immunoglobulin receptor binding activity; and protein homodimerization activity. Predicted to be involved in several processes, including B cell activation; negative regulation of complement activation, classical pathway; and type I interferon-mediated signaling pathway. Predicted to act upstream of or within with a negative effect on complement activation, alternative pathway. Predicted to act upstream of or within several processes, including cellular response to lipopolysaccharide; immunoglobulin mediated immune response; and skeletal system development. Located in cell surface and extracellular space. Human ortholog(s) of this gene implicated in common variable immunodeficiency 7; nasopharynx carcinoma; and systemic lupus erythematosus. Orthologous to human CR2 (complement C3d receptor 2). [provided by Alliance of Genome Resources, Nov 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.
