FADD Proteins

FADD (Fas Associated Via Death Domain) is a Protein Coding gene. Diseases associated with FADD include Infections, Recurrent, With Encephalopathy, Hepatic Dysfunction, And Cardiovascular Malformations and Otodental Dysplasia. Among its related pathways are Apoptosis and survival Caspase cascade and CDK-mediated phosphorylation and removal of Cdc6. Gene Ontology (GO) annotations related to this gene include identical protein binding and protease binding.

CUSABIO has five systems (E. coli, In vitro E.coli, Yeast, Insect Baculovirus, Mammalian) from prokaryotic to eukaryotic to express the recombinant protein, and a very strict QC system so that the quality can be guaranteed. And the following FADD proteins are produced under the system.
FADD proteins produced by CUSABIO are featured with high purity, low endotoxin, multi-Sources & tags, animal-free, etc. And you will have many choices on sizes from μg to mg. In addition, FADD custom service is also available for research with more specific needs.

FADD Background

FAS-associated death domain protein (FADD), also known as MORT1, is an adapter protein essential for the induction of extrinsic apoptosis. FADD contains a C-terminal death domain (DD) and an N-terminal death effector domain (DED) [1]. During extrinsic apoptosis, FADD acts as a bridge between the ligated death receptor and the caspases that directly propagate apoptotic signals. The receptors of the tumor necrosis factor (TNF) superfamily such as the FAS receptor, interacts with its cognate ligand to form a trimer complex. FADD binds to the FAs receptor trimer through its DD [2][3]. FADD is activated and subsequently recruits apoptotic pro-caspases via DED/DED interactions to form the death-inducing signal complex (DISC), which allows cleavage and activation of initiator caspases-8 and caspases-10, ultimately leading to the apoptotic response [4]. FADD is also involved in initiating necroptosis with serine/threonine kinases RIPK1 and RIPK3 [5]. Apart from being an essential component in death receptor-mediated apoptosis, FADD is required for T-cell proliferation, cell cycle progression, tumor development, inflammation, innate immunity, and autophagy [6]. It has been confirmed that apoptosis is dysregulated in various pathological conditions. In cancer, loss of FADD is beneficial to the survival of malignant tumor cells by preventing apoptosis. Elevated FADD expression has been detected in human lung cancer and is correlated with poor survival [7]. FADD expression is increased in white blood cells of multiple sclerosis relapsing patients, suggesting that FADD functions in the underlying inflammatory processes [8]. And overexpression of FADD and caspase-8 may play a role in TNF-mediated apoptosis of dopaminergic neurons of patients with Parkinson's disease [9]. In terms of FADD's role in numerous cell death processes, it is promising to be a therapeutic target in many conditions such as malignancy, autoimmunity, and inflammation. Marín-Rubio JL et al.proposed that FADD expression and phosphorylation may be reliable biomarkers with prognostic value for T-cell lymphoblastic lymphoma (T-LBL) stratification [10].
