'''Brain Tumor NHL domain'''<br />

==Overview==

The Brain Tumor (Brat) protein is recruited to the 3' untranslated region, (UTR) of hunchback mRNA to regulate its translation. Recruitment is, mediated by interactions between the Pumilio RNA-binding Puf repeats and, the NHL domain of Brat, a conserved structural motif present in a large, family of growth regulators. In this report, we describe the crystal, structure of the Brat NHL domain and present a model of the Pumilio-Brat, complex derived from in silico docking experiments and supported by, mutational analysis of the protein-protein interface. A key feature of the, model is recognition of the outer, convex surface of the Pumilio Puf, domain by the top, electropositive face of the six-bladed Brat, beta-propeller. In particular, an extended loop in Puf repeat 8 fits in, the entrance to the central channel of the Brat beta-propeller. Together, these interactions are likely to be prototypic of the recruitment, strategies of other NHL-containing proteins in development.
