Synonyms: Anti-Protein Z39Ig; Anti-V-set and immunoglobulin domain-containing protein 4
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: V-set and immunoglobulin domain containing 4 (VSIG4) is a new inhibitor of the B7 superfamily. It is referred to as CRIg and Z39IG. It is implicated in the clearance of systemic pathogens and autologous cells. It is exclusively expressed on tissue resident macrophages and binds to multimers of C3b and iC3b that are covalently attached to particle surfaces. Its extracellular domain inhibits complement activation through the alternative pathways and function as an important clearance receptor. It also acts as a potential diagnostic marker of severe preeclampsia.
