Death Domain Associated Protein / DAP6 (Daxx) Antibody

Background

Death-Associated Protein 6 (DAXX) is a multifunctional protein involved in apoptosis regulation, transcriptional control, and chromatin remodeling. Initially identified as a Fas-binding protein, DAXX can mediate apoptotic signals in response to Fas receptor activation, playing a role in programmed cell death. In addition to its role in apoptosis, DAXX functions as a transcriptional co-repressor, interacting with various transcription factors to modulate gene expression. DAXX is also a key component of the chromatin remodeling machinery, where it interacts with histone chaperones and contributes to histone deposition and nucleosome assembly. It is localized to promyelocytic leukemia nuclear bodies (PML-NBs) and telomeres, where it participates in DNA damage responses and telomere maintenance. Dysregulation of DAXX is linked to cancer, as it can act as a tumor suppressor or promoter depending on the cellular context. Mutations in DAXX are frequently observed in pancreatic neuroendocrine tumors and other cancers, where they contribute to genomic instability and altered gene expression. DAXX is being investigated as a therapeutic target due to its diverse roles in apoptosis, chromatin dynamics, and tumorigenesis.
