Phospho-TNFR(S274) Antibody

Peptide Affinity Purified Rabbit Polyclonal Antibody (Pab)

  • WB - Phospho-TNFR(S274) Antibody AP3274a
    Western blot analysis of hTNFR-pS274 (Cat. #AP3274a) in MDA-MB468 cell line lysates (35ug/lane). TNFR (arrow) was detected using the purified Pab.
  • IHC-P - Phospho-TNFR(S274) Antibody AP3274a
    Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.

Protein Information
Synonyms TNFAR, TNFR1
Function Receptor for TNFSF2/TNF-alpha and homotrimeric TNFSF1/lymphotoxin-alpha. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate- specific cysteine proteases) mediating apoptosis. Contributes to the induction of non-cytocidal TNF effects including anti-viral state and activation of the acid sphingomyelinase.
Cellular Location Cell membrane; Single-pass type I membrane protein Golgi apparatus membrane; Single- pass type I membrane protein Secreted. Note=A secreted form is produced through proteolytic processing

A member of the TNF-receptor superfamily, this protein is one of the major receptors for the tumor necrosis factor-alpha. This receptor can activate NF-kappaB, mediate apoptosis, and function as a regulator of inflammation. Antiapoptotic protein BCL2-associated athanogene 4 (BAG4/SODD) and adaptor proteins TRADD and TRAF2 have been shown to interact with this receptor, and thus play regulatory roles in the signal transduction mediated by the receptor. Germline mutations of the extracellular domains of this receptor were found to be associated with the autosomal dominant periodic fever syndrome. The impaired receptor clearance is thought to be a mechanism of the disease.
