International Journal for Parasitology, 2008 RNA-binding proteins play key roles in post-transcriptional regulation of gene expression. In eukaryotic cells, a multitude of RNA-binding proteins with several RNA-binding domains/motifs have been described.

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

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 ...

Expression of a mitochondrial stress protein in the protozoan parasite Leishmania major
Journal of Cell Science, 1993ABSTRACT The DNA sequence has been determined of a gene from Leishmania major that shares sequence identity with members of the eukaryotic heat shock protein (hsp) 70 gene family. The deduced open reading frame for translation shares a number of features common to hsp70 stress proteins, including conserved amino acids implicated in ATP ...

Large‐scale survey for potentially targetable indels in bacterial and protozoan proteins
Proteins: Structure, Function, and Bioinformatics, 2005AbstractOur previous results demonstrated that some essential, housekeeping proteins from pathogenic microorganisms may contain sizable insertions–deletions in their sequences (compared to close human homologs) that can be responsible for unexpected virulence properties.

In silico identification of the protein disulfide isomerase family from a protozoan parasite
Computational Biology and Chemistry, 2008Protein disulfide isomerase (PDI) enzymes are eukaryotic oxidoreductases that catalyze the correct formation of disulfide bonds during protein folding. Structurally they are characterized by the presence of functional thioredoxin-like (Trx) domains.

Characterization of Trichomonas vaginalis virus proteins in the pathogenic protozoan T. vaginalis
Archives of Virology, 1998The 4.6-kb double-stranded (ds) RNA of Trichomonas vaginalis virus (TVV)-T1 has been shown to encode two overlapping genes, cap and pol. In this study, a serum for specifically detecting viral cap gene product was raised against a recombinant protein, and sera for specifically detecting pol gene product were raised against synthetic oligopeptides. A 75-

Heat Shock Proteins in Protozoan Parasites – Leishmania spp.
2009In this review, we shall look into the heat shock proteins of kinetoplastid protozoa of the genus Leishmania. The leishmaniae possess a full complement of molecular chaperones, with peculiar additions. Heat shock proteins play crucial roles in both parts of the biphasic life cycle, having an impact, both on the temperature-induced differentiation from ...

Recombinant Protein Production in the Eukaryotic Protozoan Parasite Leishmania tarentolae: A Review
2011Leishmania tarentolae is a trypanosomatid protozoan parasite of the gecko, and has been established as a new eukaryotic expression system for the production of recombinant proteins. It seems that a protozoan parasite is a curious choice as the expression host; however, Trypanosomatidae are rich in glycoproteins with a pattern of glycosylation closely ...
