Noxa (Latin for damage) is a pro-apoptotic member of the Bcl-2 protein family.^[6] Bcl-2 family members can form hetero- or homodimers, and they act as anti- or pro-apoptotic regulators that are involved in a wide variety of cellular activities. The expression of Noxa is regulated by the tumor suppressor p53, and Noxa has been shown to be involved in p53-mediated apoptosis.
