Also known as: C4BP
Summary: Predicted to enable complement binding activity. 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 act upstream of or within binding activity of sperm to zona pellucida. Predicted to be located in acrosomal matrix; cell body; and outer acrosomal membrane. Predicted to be part of zona pellucida receptor complex. Predicted to be active in extracellular space and plasma membrane. 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, Jan 2025]

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.
