  • General notesStable for one year.


    Fas and Tumor Necrosis Factor Receptor 1 (TNFR 1) are two prototype members in the death receptor family. A novel protein that associates with the intracellular domains of Fas and TNFR 1 was recently identified and designated F1A alpha and FEM 1 beta. F1Aa/FEM1b is the homologue of C. elegans sex determining protein FEM 1. FEM 1/F1Aa is cleaved by CED-3 and caspase. FEM 1/F1Aa associates with CED-4 and its mammalian homologue Apaf 1. Overexpression of F1Aa induces apoptosis. F1Aa is therefore a novel member of the death receptor associated protein that mediates apoptosis. F1Aa is expressed in a variety of human and mouse tissues.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.5 - 1 µg/ml. Predicted molecular weight: 70 kDa.Can be blocked with FEM 1B peptide (ab6098).
ICC/IF Use a concentration of 20 µg/ml.
IHC-P Use a concentration of 5 µg/ml.

Target

  • FunctionComponent 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.
  • Tissue specificityWidely expressed. Highly expressed in testis. Weakly expressed in other tissues.
  • PathwayProtein modification; protein ubiquitination.
  • Sequence similaritiesBelongs to the fem-1 family.
    Contains 8 ANK repeats.
    Contains 1 TPR repeat.
  • Cellular localizationCytoplasm. Nucleus. In the nucleus, the protein level increased slightly after camptothecin (CPT) treatment. Associated with chromatin.
