    Summary
    Predicted to be involved in several processes, including negative regulation of complement activation, classical pathway; regulation of opsonization; and response to symbiotic bacterium. Predicted to be located in extracellular region. Predicted to be active in extracellular space and plasma membrane. Is expressed in foregut-midgut junction; midgut; midgut loop; renal calyx; and renal pelvis. Human ortholog(s) of this gene implicated in COVID-19. Orthologous to human C4BPA (complement component 4 binding protein alpha). [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.
