Recombinant Human Fas protein, His-tagged

• Cat.No.: Fas-027H
• Product Overview: Recombinant Human Fas (Gln26-Asn173) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Description: The Fas is also known as FAS receptor (FasR), apoptosis antigen 1 (APO-1 or APT), cluster of differentiation 95 (CD95) or tumor necrosis factor receptor superfamily member 6 (TNFRSF6). is a death receptor on the surface of cells that leads to programmed cell death (apoptosis). It is one of two apoptosis pathways, the other being the mitochondrial pathway. FasR is located on chromosome 10 in humans and 19 in mice. Similar sequences related by evolution (orthologs) are found in most mammals. Fas forms the death-inducing signaling complex (DISC) upon ligand binding. Membrane-anchored Fas ligand trimer on the surface of an adjacent cell causes trimerization of Fas receptor. This event is also mimicked by binding of an agonistic Fas antibody, though some evidence suggests that the apoptotic signal induced by the antibody is unreliable in the study of Fas signaling. To this end, several clever ways of trimerizing the antibody for in vitro research have been employed.Upon ensuing death domain (DD) aggregation, the receptor complex is internalized via the cellular endosomal machinery. This allows the adaptor molecule FADD to bind the death domain of Fas through its own death domain. Recently, Fas has also been shown to promote tumor growth, since during tumor progression, it is frequently downregulated or cells are rendered apoptosis resistant. Cancer cells in general, regardless of their Fas apoptosis sensitivity, depend on constitutive activity of Fas. This is stimulated by cancer-produced Fas ligand for optimal growth.

Q&As

Does FAS protein play a role in cell signaling?

FAS protein plays an important role in cell signaling, it can activate downstream signaling pathways, such as death signaling pathway and survival signaling pathway, by binding to its ligand and transmitting signals.

Why apply knowledge of FAS proteins to clinical practice?

It can provide a reference for clinical practice and guide the diagnosis, treatment and prevention of diseases by detecting the expression level of FAS protein and understanding its mechanism of action.

How can diseases associated with FAS protein be prevented and treated?

FAS protein-related diseases can be prevented and treated by regulating the expression level of FAS protein and inhibiting its signaling pathway.

How can gene knockout or knockdown techniques be used to study the function of FAS proteins?

Gene knockout or knockdown techniques can be used to study the function and mechanism of action of FAS proteins. By knocking out or knocking down the FAS gene, changes in processes such as apoptosis and immune response can be observed to further understand its function and mechanism of action.

What is the role of FAS protein in apoptosis?

FAS protein can bind to its ligand, activate the death signaling pathway, and induce apoptosis.

How can FAS protein be used to predict disease prognosis?

The expression level and activity of FAS protein can be measured to predict the prognosis and development trend of certain diseases.
