Human VSIG4/CRIg HEK293T Stable Cell Line

Introduction
Human VSIG4/CRIg is a transmembrane glycoprotein that belongs to the immunoglobulin superfamily. It is also known as complement receptor of the Ig superfamily (CRIg) and is primarily expressed on macrophages and dendritic cells. VSIG4/CRIg is involved in the regulation of immune response and plays a crucial role in the pathogenesis of various diseases. In this article, we will discuss the structure, activity, and applications of the Human VSIG4/CRIg HEK293T Stable Cell Line.

Structure of Human VSIG4/CRIg
The Human VSIG4/CRIg protein is composed of 349 amino acids and has a molecular weight of approximately 40 kDa. It consists of an extracellular domain, a transmembrane domain, and a cytoplasmic domain. The extracellular domain contains two Ig-like domains, with the N-terminal domain being responsible for ligand binding. The transmembrane domain anchors the protein to the cell membrane, while the cytoplasmic domain is involved in signal transduction.

Activity of Human VSIG4/CRIg
Human VSIG4/CRIg is a complement receptor that binds to the complement component C3b and its cleavage product, iC3b. This binding inhibits the activation of the complement cascade and prevents the formation of the membrane attack complex. Additionally, VSIG4/CRIg also plays a role in the phagocytosis of opsonized pathogens and apoptotic cells by macrophages and dendritic cells. It also regulates the production of pro-inflammatory cytokines, such as TNF-α and IL-6, by modulating the activity of Toll-like receptors.
