Abstract: Pdcd4 (Programmed Cell Death Protein 4) is a novel eukaryotic tumour suppressor protein, which is involved in the regulation of both transcription and translation (reviewed in Lankat-Buttgereit and Göke 2009). The protein contains two interacting MA-3 domains (MA-3M and MA-3C), which are linked by a short semi-flexible linker region (Waters et al. 2007; Suzuki et al. 2008). The MA-3 domains are involved in mediating specific protein–protein interactions with functional partners such as eIF4A (Yang et al. 2003 ). Here we report essentially complete backbone and side chain 15N, 13C and 1H assignments for a construct composed of the middle MA-3 domain and subsequent linker region (MA-3M) and backbone assignments for the entire tandem MA-3 region of Pdcd4 (Pdcd4 MA-3M-C). Analysis of the backbone chemical shift data obtained indicates that Pdcd4 MA-3M contains eight helical regions corresponding to over 74% of the protein backbone and that Pdcd4 MA-3M-C contains fifteen helical regions (72%). Comparison of the position of these helical regions with those observed in the crystal structures suggests that the solution and crystal structures of both proteins are very similar.
