Description

Death-domain associated protein, also known as DAP6 (Death-associated protein 6), Daxx and BING2, was first discovered through its cytoplasmic interaction with the classical death receptor Fas. The gene encodes a 740-amino acid polypeptide containing a nuclear localization signal. Functional analyses by Yang et al.(1997) demonstrated that Daxx binds to the Fas death domain and enhances Fas-mediated apoptosis. The authors suggested that DAXX and FADD define 2 distinct apoptotic pathways downstream of Fas. The gene is mapped to human chromosome 6p21.3 by somatic cell hybrid panels and fluorescence in situ hybridization, a region containing the HLA and putative autoimmune disease genes. MSP58 overexpression relieved DAXX-mediated transcriptional repression. Immunoprecipitation and Western blot analysis with DAXX mutants showed that the N terminus of the protein interacts with the C terminus of DMAP. Transient expression of DAXX or DMAP1 caused repression of glucocorticoid receptor-mediated transcription.

Application Notes

The stated application concentrations are suggested starting amounts. Titration of the Daxx antibody may be required due to differences in protocols and secondary/substrate sensitivity.

Immunogen

Amino acids 325-341 (QERRHLDLIYNFGCHLT) were used as the immunogen for this Daxx antibody (100% homologous in human, mouse and rat).

Storage

After reconstitution, the Daxx antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
