    ABSTRACT: Hereditary spastic paraplegia (HSP) is a group of neurodegenerative diseases. The genotypes and phenotypes of HSP are extremely heterogenous. SPG3A is one of the identified genes underlying HSP, and codes for a GTPase, atlastin. Mutations in SPG3A are currently believed to be associated with early onset and mild phenotypes. And most structural predictions could not detect gross changes in the mutant protein. However, in a severely affected HSP family we have identified a novel SPG3A mutation, c.1228G>A (p.G410R), in a Tibetan kindred. The mutation occurred at the highly conserved nucleotide and co-segregated with the disease, and was absent in the control subjects. Structural predictions showed that the Tibetan mutation occurred at the linking part between the guanylate-binding protein domain (GB, the ball region) and the transmembrane helices (TM, the rod region) at the start point of an α-helix, which may disrupt the helix, and cause changes in the overall structure of the transmembrane region of the molecule. Our results indicate that severe phenotypes can also arise from SPG3A mutations and the linking part of the guanylate-binding protein domain and the transmembrane helices might be crucial in determining the severity of the disease. This paper not only presents the first SPG3A mutational report from the Chinese population, but also provides potential evidence for a possible correlation between the severity of the phenotypes of HSP with the extension of the changes in the protein structures of atlastin.

    ABSTRACT: There is a large gap between the number of membrane protein (MP) sequences and that of their decoded 3D structures, especially high-resolution structures, due to difficulties in crystal preparation of MPs. However, detailed knowledge of the 3D structure is required for the fundamental understanding of the function of an MP and the interactions between the protein and its inhibitors or activators. In this paper, some computational approaches that have been used to predict MP structures are discussed and compared.

    ABSTRACT: Alternative splicing is an important cellular mechanism that increases the diversity of gene products. The number of alternatively spliced genes reported so far in plants is much smaller than that in mammals, but is increasing as a result of the explosive growth of available EST and genomic sequences. We have searched for all alternatively spliced genes reported in GenBank and PubMed in all plant species under Viridiplantae. After careful merging and manual review of the search results, we obtained a comprehensive, high-quality collection of 168 genes reported to be alternatively spliced in plants, spanning 44 plant species (March 22, 2003 update). We developed a relational database with Web-based user interface to store and present the data, named the Plant Alternative Splicing Database (PASDB), freely available at We analyzed the functional categories that these genes belong to using the Gene Ontology. We also analyzed in detail the biological roles and gene structures of the four genes that are known to be alternatively spliced in more than one plant species. Finally, we studied the structural features of the splice sites in the alternatively spliced genes.
