Protein and RNA inhibitors and protozoan habituation
Psychopharmacologia, 1970A variety of protein and RNA inhibitors were tested on habituation learning in the protozoan Spirostomum. Inhibition of protein synthesis up to values of 95% had no effect upon habituation, and RNA inhibition up to 89% by 5-fluorouracil had only slight effects upon it. Large amounts of protein and RNA synthesis are not necessary for habituation.

Isoprenylation of proteins in the protozoan Giardia lamblia
Molecular and Biochemical Parasitology, 1995We report the ability of Giardia lamblia to modify several of its cellular proteins by isoprenylation. Trophozoites cultured in the presence of [3H]mevalonate synthesized radiolabeled proteins of approx. 50 and 21-26 kDa. Chemical analysis indicated that farnesyl and geranylgeranyl isoprenoids comprised the majority of the radiolabel covalently ...

The Cell Type-Specific Signal Proteins (Pheromones) of Protozoan Ciliates
Current Pharmaceutical Design, 2006In association with their mechanisms of self/non-self recognition (known as mating type systems), ciliates synthesize and constitutively secrete cell type-specific proteins into their extracellular medium. These proteins, designated as pheromones, have been isolated from species of Euplotes and shown to be members of families of structurally homologous

Dna-Protein Interactions at Telomeres in Ciliated Protozoans
Advances in Molecular and Cell Biology, 1988Publisher Summary This chapter discusses the DNA–protein complexes found at telomeres in the macronuclei of ciliated protozoans, with special attention given to studies in Oxytricha (a hypotrichous ciliate) and Tetrahymena (a holotrichous ciliate). The structure of telomeres has been largely elucidated by studies on macronuclear DNA from ciliated

Glycosylation of proteins in the protozoan Euglena gracilis
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985Abstract 1. 1. The main dolichol-P-P-bound oligosaccharide present in Euglena gracilis cells incubated with [U- 14 C]glucose was found to migrate on paper chromatography as a Glc 3 Man 9 GlcNAc 2 standard and to contain glucose, mannose and N- acetylglucosamine residues. 2. 2.

Pore-forming proteins in pathogenic protozoan parasites
Trends in Microbiology, 1997Pore-forming proteins (PFPs) may play important roles in pathogenesis by protozoan parasites by either directly damaging the plasma membrane of the host cells or ensuring intracellular survival of the parasites by promoting their exit from lysosomal vacuoles.

Protein synthesis and cell division in a pyrimidine-starved protozoan
Experimental Cell Research, 1960Abstract In media complete save for uracil, T. pyriformis continues to make protein, divide, and form normal cells, although its net RNA content does not increase. Uracil-starved cells rapidly regain their original RNA level when uracil is restored.

Protein synthesis by kinetosomes isolated from the protozoan Tetrahymena
Biochimica et Biophysica Acta (BBA) - Specialized Section on Nucleic Acids and Related Subjects, 1962Abstract An increase in biuret-positive material occurs when kinetosomes isolated from the ciliated protozoan Tetrahymena pyriformis are incubated in a mixture containing amino acids, inorganic phosphorus, uridylic acid, cytidylic acid, guanylic acid, thymine, inosine, MgSO 4 , KF, hexose-diphosphate, ATP, pteroylglutamic acid, riboflavin, vitamin ...

The role of ATP-binding cassette (ABC) proteins in protozoan parasites
Molecular and Biochemical Parasitology, 2009The ATP-binding cassette (ABC) superfamily is one of the largest protein families with representatives in all kingdoms of life. Members of this superfamily are involved in a wide variety of transport processes with substrates ranging from small ions to relatively large polypeptides and polysaccharides, but also in cellular processes such as DNA repair,

TLR11 Activation of Dendritic Cells by a Protozoan Profilin-Like Protein
Science, 2005Mammalian Toll-like receptors (TLRs) play an important role in the innate recognition of pathogens by dendritic cells (DCs). Although TLRs are clearly involved in the detection of bacteria and viruses, relatively little is known about their function in the innate response to eukaryotic microorganisms.
