In vitro folding and characterization of the p53 DNA binding domain
The transcription factor p53 acts as major tumor suppressor
and is inactivated by mutation in more than 50%
of all human tumors. We have established an efficient
procedure for the in vitro folding and purification of the
p53 DNA binding domain (p53DBD) using a modified factorial
matrix approach that supplies large amounts of
homogeneous (isotope-labeled) p53DBD for application
in biochemical, crystallographic and NMR spectroscopic
studies. We further show with biophysical methods that
in vitro folded p53DBD is fully functional and that its conformation
is identical to that obtained from the soluble
fraction.
