Interactions among a group of related proteins in the cellular slime mold 'Dictyostelium discoideum'
In previous work, the Dictyostelium discoideum gene encoding the cAMP-binding protein CABP1 was isolated and cloned. Subsequent studies revealed that certain polypeptides are related in their amino acid sequence to CABP1. Each of these polypeptides possesses a region of high glycine, tyrosine, …

Understanding the Evolution of Aggregative Multicellularity: A Molecular Phylogenetic Study of the Cellular Slime Mold Genera Sorodiplophrys and Pocheina
<p>Cellular slime molds are amoeboid protists that have a unicellular trophic phase and multicellular dispersal stage formed through the aggregation of individuals in their life cycles. These organisms were once thought to form a monophyletic group in the Mycetozoa. After careful morphological, …

Self-organized Pattern Formation using Engineered Bacteria
… natural pattern formation processes, such as slime mold aggregation, feather branching, and tissue stratification. Regardless of the specific molecular interactions, the vast majority of these mechanisms invoke morphogen gradients, which are either predefined or generated as part of the …

Uncovering the signal transduction pathway that regulates the proliferation of Dictyostelium cells
… factor that represses proliferation in the slime mold Diclyostelium discoideum . Although the role AprA plays in the regulation of proliferation is known, the signaling pathway by which it occurs is yet to be determined. To discover the different components of the AprA signaling pathway, I …

The relationship between the two forms of glycogen phosphorylase in Dictyostelium discoideum
The slime mold Dictyostelium discoideum has two developmentally regulated forms of the enzyme glycogen phosphorylase. The inactive ’b’ form requires 5'AMP for activity and is present in early development, whereas the active ’a’ form is 5'AMP independent and is present in late development. …

The relationship between two forms of glycogen phosphorylase in Dictyostelium discoideum
The cellular slime mold, Dictyortelium dixcoideum, provides an ideal model system to study eukaryotic cell differentiation. In D. discoideum glycogen degradation provides precursors for the synthesis of developmentally regulated structural end products. The enzyme responsible for glycogen …

Signal processing and decision making in single cells
… Many single celled organisms, such as the slime mold Dictyostelium discoideum, can sense and respond to concentration gradients of extracellular signaling molecules. We find that the cells' ability to detect an extracellular signal is influenced by an asymmetric intracellular signal, which …

Molecular analysis of glycogen phosphorylase-1 gene expression during the development of dictyostelium discoideum
The cellular slime mold, <i><b>Dictyostelium discoideum</i></b>, has two developmentally regulated forms of the enzyme glycogen phosphorylase, which are encoded by two distinct, but related genes (Rutherford, et. aI., 1991). A complementary DNA (cDNA) encoding glycogen phosphorylase-}, gp-l, was …

Characterization of a fatty acid elongase condensing enzyme by site-directed mutagenesis and biochemical analysis
… the condensing enzyme, EloA, from the cellular slime mold, Dictyostelium discoideum as a model for the family of ELOs. EloA has substrate specificity for monounsaturated and saturated C16 fatty acids and catalyzes the elongation of 16:1Δ9 to 18:1Δ11. Site-directed mutagenesis was used to change …

Regulation of glycogen phosphorylase genes in Dictyostelium discoideum
The cellular slime mold, Dictyostelium discoideum, provides an ideal model system to study eukaryotic development, cell differentiation, and aging. A crucial developmental event in Dictyostelium is glycogen degradation. The degradation of glycogen provides glucose monomers that are used to …

Characterization and localization of adenylate cyclase during development of Dictyostelium discoideum
… of single-celled amoebae of the cellular slime mold Dictyostelium discoideum. Evidence suggests that cyclic AMP also acts as a regulatory molecule during Dictyostelium multicellular differentiation. Biochemical characterization of adenylate cyclase, the cyclic AMP synthetic enzyme, was …

The study of ancient viral class II envelope fusion proteins within the viral retroelements of Nematoda and the nuclear plasmids of Dictyostelium
… circular, nuclear plasmids of the slime mold Dictyostelium. While these plasmids, specifically Ddp1 and Ddp5, have been used as transfer vectors in dictyostelid studies, their relation to known viruses has gone unrecognized. Like the env captured by the BEL/Pao LTR retrotransposons …

Phototaxis of Dictyostelium discoideum Slugs
During the slug stage of cellular slime mold Dictyostelium discoideum, up to 105 cells coordinate their movement and migrate as a single organism. Slugs have a cylindrical shape with tip and tail; their morphological polarity corresponds to the polarity of migration. A large body of results suggest …

Function of a C-rich region in the transcriptional regulation of the glycogen phosphorylase-2 gene in Dictyostelium discoideum
The cellular slime mold Dictyostelium discoideum is a simple eukaryote that has been used as a model organism for the investigation of eukaryotic cell signaling, regulation of gene expression, and development. Transcription of the gp-2 gene is induced during development and is regulated by …
