Fas Detection Service

Fas is a transmembrane protein involved in the signal transduction pathway of apoptosis, and the signal transduction pathway mediated by it is essential for the maintenance of immune system homeostasis. Fas is an important biomarker involved in the research of immune-related diseases. Creative BioMart Biomarker provides fast, efficient, and sensitive Fas testing services for customers engaged in disease research and basic research to help advance customers' related research. Our service is not suitable for private medical diagnosis and testing.

Fas and Immune System

Fas, also known as cluster of differentiation 95 (CD95), apoptosis antigen 1 (APO-1), and tumor necrosis factor receptor superfamily member 6 (TNFRSF6), is a transmembrane protein that can trigger apoptosis signal transduction pathways. Fas is a death receptor located on the surface of a variety of cells. It is encoded by the FAS gene and belongs to the tumor necrosis factor (TNF) receptor family. Fas protein contains three domains, which are a cysteine-rich extracellular domain, a transmembrane domain consisting of 17 amino acids, and a cytoplasmic domain consisting of 145 amino acids and containing a death domain (DD). Fas interacts with its ligand FasL (a member of the TNF family) to activate the caspase cascade, thereby inducing the initiation of apoptosis. FasL is a 40kDa protein located on the membrane. FasL can recruit the adaptor protein Fas-associated death domain (FADD), combine with procaspase-8, and form a death-inducing signal complex (DISC). Activated caspase-8 can directly cleave caspase-3 and trigger the initiation of the caspase cascade, which ultimately leads to cell death. Fas-FasL participates in many physiological and pathological processes mediated by programmed cell death, and plays an important role in maintaining immune homeostasis. The Fas-FasL-mediated cell death signal pathway plays an important role in the deletion of autoreactive lymphocytes during the development of the immune system and the deletion of activated lymphocytes during the immune response. Therefore, Fas-mediated apoptosis plays a key role in the immune system, and it also has research value in immune-related diseases, such as multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis.
