what is bax
Apoptosis regulator BAX, also known as bcl-2-like protein 4, is a protein that in humans is encoded by the BAX gene. BAX is a member of the Bcl-2 gene family.BCL2 family members form hetero-or homodimers and act as anti-or pro-apoptotic regulators that are involved in a wide variety of cellular activities.This protein forms a heterodimer with BCL2, and functions as an apoptotic activator.he BAX gene was the first identified pro-apoptotic member of the Bcl-2 protein family. Bcl-2 family members share one or more of the four characteristic domains of homology entitled the Bcl-2 homology (BH) domains (named BH1, BH2, BH3 and BH4), and can form hetero-or homodimers.
