DAXX (human)

DAXX a transcriptional co-regulatory protein. Proposed to mediate activation of the JNK pathway and apoptosis via ASK1 in response to signaling from FAS and TGF-betaR2. Glucose deprivation activates the ASK1-SEK1-JNK1-HIPK1 pathway, relocalizing Daxx from the nucleus to the cytoplasm, where Daxx binds to ASK1, and subsequently leads to ASK1 oligomerization. Interaction with HSP27 may prevent interaction with TGF-betaR2 and ASK1 and block DAXX-mediated apoptosis. Seems to act as a transcriptional co- repressor and inhibits PAX3 and ETS1 through direct protein- protein interaction. Its transcription repressor activity is modulated by recruiting it to subnuclear compartments like the nucleolus or PML/POD/ND10 nuclear bodies through interactions with MCSR1 and PML, respectively. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
