Brain Tumor NHL domain

Structural highlights

1q7f is a 2 chain structure with sequence from Drome. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	brain tumor (DROME)

Function

[BRAT_DROME] Plays a central role in translation repression of hb mRNA by being recruited by nos and pum to the Nanos Response Element (NRE), a 16 bp sequence in the hb mRNA 3'-UTR. Probably recruited by other proteins to repress translation of other mRNAs in other tissues. Involved in the regulation of ribosomal RNA synthesis and cell growth. Participates in abdominal segmentation and imaginal disk development. Involved in brain tumor suppression, by acting as a growth suppressor in the larval brain.^[1] ^[2]

Publication Abstract from PubMed

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.
