Developmental regulation of the Tetrahymena thermophila origin recognition complex. [PDF]

PLoS Genetics, 2015
The Tetrahymena thermophila DNA replication machinery faces unique demands due to the compartmentalization of two functionally distinct nuclei within a single cytoplasm, and complex developmental program.

Biodiversity modulates the cross‐community scaling relationship in changing environments

Ecology Letters, Volume 28, Issue 9, September 2025.
Organismal abundance typically declines with increasing body size, with metabolic theory predicting a universal size–abundance slope of –0.75. Using protist microcosms across gradients of species richness, temperature and time, we found that while the expected slope is broadly supported, it is not invariant. Warming and biodiversity interacted to alter

Exploring the Histone Acetylation Cycle in the Protozoan Model Tetrahymena thermophila

Frontiers in Cell and Developmental Biology, 2020
The eukaryotic histone acetylation cycle is composed of three classes of proteins, histone acetyltransferases (HATs) that add acetyl groups to lysine amino acids, bromodomain (BRD) containing proteins that are one of the most characterized of several ...

Purification and characterisation of cell survival factor 1 (TCSF1) from Tetrahymena thermophila [PDF]

, 2007
Of a number of peptides isolated from the extracellular medium of Tetrahymena cultures, two with masses 9.9 and 22.4 kDa allowed low-density cultures of this ciliate to survive and enter a proliferate phase.

Re‐evaluation of PTEN as an ADP‐ribosylated tankyrase binding partner

The FEBS Journal, Volume 292, Issue 17, Page 4611-4630, September 2025.
We reveal that PTEN and its conserved putative tankyrase‐binding motif (pTBM) originated before tankyrases in evolution. We demonstrate that the pTBM shows no binding to tankyrase ARC domains, but it has structural and functional roles. We show, using recombinant proteins, that PTEN is not a tankyrase binding partner and substrate, and that catalytic ...

Progeny of Germ Line Knockouts of \u3cem\u3eASI2\u3c/em\u3e, a Gene Encoding a Putative Signal Transduction Receptor in \u3cem\u3eTetrahymena Thermophila\u3c/em\u3e, Fail to Make the Transition from Sexual Reproduction to Vegetative Growth [PDF]

, 2006
The ciliated protozoan Tetrahymena has two nuclei: a germ line micronucleus and a somatic macronucleus. The transcriptionally active macronucleus has about 50 copies of each chromosome.

Effects of ytterbium ion on the growth, metabolism and membrane fluidity of Tetrahymena thermophila [PDF]

, 2007
Power-time curves and metabolic properties of Tetrahymena thermophila BF5 exposed to different Yb3+ stop levels were studied by ampoule method of isothermal calorimetry at 28 degrees C.

Two Centrins and Their Posttranslational Modification Modulate the Cell Cycle of Giardia lamblia

MicrobiologyOpen, Volume 14, Issue 4, August 2025.
Two Giardia lamblia centrins (Glcents) play a role in cell cycle progression and morphogenesis of Giardia. Both Glcents are substrates of GlSUMO, suggesting a role of SUMOylation in their proper localization. SUMOylation is also involved in regulating vacuole formation in Giardia.

Analysis of the genes and mechanisms responsible for the cytotoxicity of the Legionella Ofk308 strain in the Tetrahymena host

Frontiers in Microbiology
BackgroundLegionella pneumophila, an intracellular pathogen responsible for the pneumonia-like Legionnaires’ disease in humans, inhabits aquatic environments, including man-made water systems such as water fountains, foot spas, and tap water, and exists ...

The telomerase essential N-terminal domain promotes DNA synthesis by stabilizing short RNA-DNA hybrids. [PDF]

, 2015
Telomerase is an enzyme that adds repetitive DNA sequences to the ends of chromosomes and consists of two main subunits: the telomerase reverse transcriptase (TERT) protein and an associated telomerase RNA (TER). The telomerase essential N-terminal (TEN)
