Summary: Enables complement component C5a binding activity and complement component C5a receptor activity. Involved in several processes, including animal organ regeneration; negative regulation of neuron apoptotic process; and response to lipopolysaccharide. Located in cell surface. Used to study adult respiratory distress syndrome; amyotrophic lateral sclerosis; neutropenia; obesity; and thrombosis. Biomarker of asthma and lung disease. Orthologous to human C5AR1 (complement C5a receptor 1). [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.
