|Application Notes||F1Ab antibody can be used for detection of F1Ab by Western blot at 1 μg/mL. An approximately 70 kDa band can be detected. Antibody can also be used for immunohistochemistry starting at 5 μg/mL. For immunofluorescence start at 20 μg/mL.|
|Other Names||F1A alpha Antibody: F1AA, F1A-ALPHA, FEM1-beta, F1AA, KIAA0396, Protein fem-1 homolog B, FEM1b, fem-1 homolog b (C. elegans)|
|Target/Specificity||F1A antibody was raised against a 14 amino acid peptide near the carboxy terminus of human F1A.|
The immunogen is located within the last 50 amino acids of F1A alpha.
|Reconstitution & Storage||F1A alpha 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.|
|Precautions||F1A alpha Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Component of an E3 ubiquitin-protein ligase complex, in which it may act as a substrate recognition subunit. Involved in apoptosis by acting as a death receptor-associated protein that mediates apoptosis. Also involved in glucose homeostasis in pancreatic islet. Functions as an adapter/mediator in replication stress-induced signaling that leads to the activation of CHEK1.|
|Cellular Location||Cytoplasm. Nucleus. Note=In the nucleus, the protein level increased slightly after camptothecin (CPT) treatment. Associated with chromatin|
|Tissue Location||Widely expressed. Highly expressed in testis. Weakly expressed in other tissues.|

F1A alpha Antibody: Fas and tumor necrosis factor receptor 1 (TNFR1) are two prototype members in the death receptor family. A novel protein that associates with the intracellular domains of Fas and TNFR1 was recently identified and designated F1Aalpha and FEM1β. F1Aalpha/FEM1β is the homologue of C. elegans sex determining protein FEM-1. FEM-1/F1Aalpha is cleaved by CED-3 and caspase. FEM-1/F1Aalpha associates with CED-4 and its mammalian homologue Apaf-1. Overexpression of F1Aalpha induces apoptosis. F1Aalpha is therefore a novel member of the death receptor associated protein that mediates apoptosis. F1Aalpha is expressed in a variety of human and mouse tissues.
