Anti-TOX-3 (Clone: ABM44A1)

TOX high mobility group box family member 3 (TOX-3) is a member of a subfamily of transcription factors that contains a High Mobility Group box (HMG-box), involved in bending and unwinding of DNA and alteration of chromatin structure. It has two transcript variants encoding different isoforms.TOX3 is expressed in estrogen receptor-positive mammary epithelial cells, including progenitor cells and highly expressed in luminal B breast cancers. Its over expression in human oligodendrocytes reduced cellular death under conditions mimicking Spinal cord injury (SCI). Protein function: Transcriptional coactivator of the p300/CBP-mediated transcription complex. Activates transactivation through cAMP response element (CRE) sites. Protects against cell death by inducing antiapoptotic and repressing pro-apoptotic transcripts. Stimulates transcription from the estrogen-responsive or BCL-2 promoters. Required for depolarization-induced transcription activation of the C-FOS promoter in neurons. Associates with chromatin to the estrogen-responsive C3 promoter region. [The UniProt Consortium]
