Additional Information
Gene ID 9214
Other Names Toso Antibody: FCMR, TOSO, Fas apoptotic inhibitory molecule 3, Regulator of Fas-induced apoptosis Toso, Fas apoptotic inhibitory molecule 3
Target/Specificity Toso antibody was raised against a 13 amino acid synthetic peptide from near the carboxy terminus of human Toso.

The immunogen is located within the first 50 amino acids of Toso.
Reconstitution & Storage Toso antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
PrecautionsToso Antibody is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name FCMR (HGNC:14315)
Synonyms FAIM3, TOSO
Function May play a role in the immune system processes. Protects cells from FAS-, TNF alpha- and FADD-induced apoptosis without increasing expression of the inhibitors of apoptosis BCL2 and BCLXL. Seems to activate an inhibitory pathway that prevents CASP8 activation following FAS stimulation, rather than blocking apoptotic signals downstream. May inhibit FAS-induced apoptosis by preventing CASP8 processing through CFLAR up-regulation.
Cellular Location Isoform 1: Membrane; Single-pass membrane protein
Tissue Location Expressed in lymph nodes, peripheral blood leukocytes, lung, thymus and kidneys. Very weak expression detected in spleen, liver, heart, and salivary gland. Expressed in lymphoid cell lines such as Jurkat, CEM-T4, MOLT-4, HB11;19 and Reh. No expression detected in nonhematopoietic cell lines including Hep-G2, HEK293 and HeLa. Detected at high levels in chronic lymphocytic leukemia cells.

Toso Antibody: Apoptosis is an important process by which normal tissue homeostasis and function are maintained. One of the major signals that regulate this process is mediated by the activation of the Fas receptor by its ligand. This leads to the formation of a Fas-associated death domain (FADD)- containing death-inducing signaling complex and the activation of caspase-8, which in turn activates downstream effector caspases, such as caspase-3 and -7. Recent experiments have shown that overexpression of Toso, a novel regulator of Fas-induced apoptosis in lymphoid cells, in Jurkat cells as well as transgenic mice render these cells resistant to Fas-induced apoptosis but not to TRAIL-induced apoptosis. Furthermore, Toso was found to associate with FADD, suggesting that Toso functions by disrupting the formation of the death-inducing signaling complex.
