FCAMR/CD351, functioning as a receptor, exhibits high-affinity binding to the Fc fragment of IgA and IgM. It plays a role in the immune response by mediating the endocytosis of IgA and IgM during the immune response to microbes. FCAMR/CD351 Protein, Mouse (HEK293, His) is the recombinant mouse-derived FCAMR/CD351 protein, expressed by HEK293 , with C-His labeled tag.
