The Brn‐5 protein plays an important role in the control of cellular development and belongs to a class of transcription factors that usually contain two domains: the POU homeodomain (POU HD ) and the POU‐specific domain (POU S ). Since high‐quality crystals suitable for crystallographic studies of the proteins of this class are difficult to obtain, all the known structural information available is for POU HD and/or POU S . This paper describes several critical steps that allowed the production of high‐quality crystals of the full‐length Brn‐5 protein complexed with its cognate DNA.
