The Multifunctional Protein Daxx: Studies Of Its Biology And Regulation, And Discovery Of A Novel Function, Trisha Agrawal
Publicly Accessible Penn Dissertations
Daxx, a multifunctional protein with a diverse set of proposed functions, is ubiquitously expressed and highly conserved through evolution. A primarily nuclear protein, Daxx is able to regulate apoptosis, transcription, and cellular proliferation. Despite many studies into the function of Daxx, its precise role in the cell remains enigmatic. Herein, evidence is presented to expand upon the known anti-apoptotic function of Daxx, to establish Daxx as a novel molecular chaperone, and to further its repertoire of transcriptional targets. As an apoptotic inhibitor, Daxx is known to regulate p53 by stabilizing its main negative regulator, Mdm2, via formation of a ternary ...
