Description

Literature Topics are a guide to the literature for a given gene and are derived from journal articles. dictyBase performs a weekly search for papers containing the terms Dictyostelium or discoideum. When dictyBase curators read those papers they assign one or more Topics that describe the kind of biological information contained in the paper. The Literature Topics are thus designed to help the user easily find the papers relevant to a given gene.

The Literature Topics

• Topic Descriptions:

  A paper is filed under one or more of the following topics if contains information about:
  
  
  • Adhesion
    Role of the gene product in cell-substrate -, or cell-cell adhesion.

  • Antibodies
    New antibodies have been published in this paper.

  • Archived Literature
    When there is extensive literature for a gene, a curator will mark a review or reviews as "Selected Review" and curate literature dating from one year prior to the date of the review. Earlier literature will be found in this topic.

  • Cell Cycle
    Cell cycle-related changes in the expression or activity of the gene product.

  • Cellular Location
    Where in the cell the protein does what it does. Information on the transport of the protein and regulation of its compartmentalization is listed under this topic.

  • Cell-type Localization
    Expression of the gene product in the multicellular organism as determined by gene-fusion or in situ hybridization experiments.

  • Chemotaxis/Motility
    Involvement of the gene product in cell movement in general, and in response to a chemical attractant.

  • Cytoskeleton
    Evidence for the protein being part of or having an effect on the cytoskeleton.

  • Development/Morphogenesis
    Studies of the gene product in morphogenesis, including all stages of multicellular development.

  • Disease Gene Related
    Homology between the Dictyostelium gene and a gene that is disease-related.

  • DNA/RNA Sequence Features
    Overall DNA sequence and DNA sequence features (promoters, exons, introns, etc.) and RNA sequence features (splice sites, poly-A sites, etc.)

  • Endocytosis
    Role of the gene product in the process of taking substances into the cell, including pinocytosis, 'macro-pinocytosis', and phagocytosis.

  • Function/Process
    The role the protein plays in the cell and what the protein is, i.e. what type of enzyme it is and if the protein functions as part of a large complex or a multi-subunit enzyme.

  • Genetic Interactions
    Interactions between loci identified by genetic means, including suppression, complementation, synthetic lethality, etc.

  • Genome-wide Analysis
    References dealing with systematic analyses of large numbers of genes, e.g. microarray studies comparing expression of all the genes in a genome in two different conditions, but not systematic sequencing papers.

  • Growth
    Role and effect of the gene product on growth rates. Includes studies of the gene product during growth as a life cycle phase.

  • List of all Curated References
    List of all references annotated to any topic for this gene.

  • Mammalian Gene Related
    Sequence and/or functional homologs of mammalian genes.

  • Mapping
    Physical or genetic mapping results.

  • Mitosis
    Describes the gene product's involvement in cytokinesis or karyokinesis.

  • Mutants/Phenotypes
    Mutations, including deletions, of the gene and resulting phenotypes.

  • Non-Mammalian Gene Related
    Sequence and/or functional homologs of non-mammalian genes.

  • Other Features
    Items that appeared important to the curator but did not fit underneath a standard topic.

  • Phtotaxis/Thermotaxis
    Phototaxis or thermotaxis of the slug has been investigated in this study.

  • Phylogenetic Analysis
    Phylogenetic analysis has been performed for this gene in this study.

  • Post-Translational Regulation
    How the protein is modified following translation, including regulatory and non-regulatory modifications, such as phosphorylation, attachment of sugars, etc.

  • Protein Functional Domain
    Features of the hypothetical or real primary amino acid sequence of the gene product (functional domains, hydropathy analysis, ion-binding sites, active sites, homology regions, etc).

  • Protein-Nucleic Acid Interactions
    Any association with DNA or RNA including direct binding or associating with other DNA- or RNA-binding proteins. This topic also includes information on binding sites. For genes that encode RNAs that do not code for proteins, for instance tRNAs, ribosomal RNAs, etc., this topic includes interactions of those RNAs with proteins.

  • Protein/Nucleic Acid Structure
    The known structure of the gene product, including known structural location of specific residues. Predictions on the structure of the protein will also be filed under this topic tag.

  • Protein Physical Properties
    The molecular weight or amino acid composition of the real or hypothetical protein product.

  • Protein-Protein Interactions
    Physical interactions that have been demonstrated between proteins by methods such as two-hybrid analysis, cross-linking studies, coimmunoprecipitation, etc., or when the abstract cites evidence for indirect or direct interactions.

  • References Not Yet Curated
    References under this topic will have been associated with this gene by the systematic search of PubMed. However, they have not yet been examined by a dictyBase curator to confirm that they are relevant to this gene or to assign other topics.

  • Regulated By
    The regulation of the gene product regulation by another protein, metabolic conditions, chemical inhibitors, or other factors. This also includes auto-regulatory functions.

  • Regulatory Role
    The role that the gene plays in regulating the activity of other genes such as by acting as a transcription factor or regulatory kinase.

  • Reviews
    Literature reviews that refer to the gene.

  • RNA Levels and Processing
    The RNA prior to translation (levels of RNA in the cell, stability, structure, splicing, etc.).

  • Selected Review
    When there is extensive literature for a gene, a curator will mark a review or review as "Selected Review" and curate literature dating from one year prior to the date of the review. Earlier literature will be found in "Archived Literature".

  • Sexual Cycle
    Role of the gene product in the sexual cycle, including mating and meiosis.
