Members containing this domain are highly conserved in species ranging from archaea to vertebrates and plants [1], including several Shwachman-Bodian-Diamond syndrome (SBDS) proteins from both mouse and humans. Shwachman-Diamond syndrome is an autosomal recessive disorder with clinical features that include pancreatic exocrine insufficiency, haematological dysfunction and skeletal abnormalities. These proteins play a role in RNA metabolism [2,3]. In yeast Sdo1 is involved in the biogenesis of the 60S ribosomal subunit and translational activation of ribosomes [4]. SBDS protein is composed of three domains. The N-terminal (Pfam:PF01172) (FYSH) domain (domain I) is the most frequent target for disease mutations and contains a novel mixed alpha/beta-fold, the central domain (domain II) represented in this entry consists of a three-helical bundle and the C-terminal domain that has a ferredoxin-like fold [3,5].
