Structural basis for binding of the renal carcinoma target hypoxia‐inducible factor 2α to prolyl hydroxylase domain 2

Proteins: Structure, Function, and Bioinformatics, Volume 91, Issue 11, Page 1510-1524, November 2023., 2023
Abstract The hypoxia‐inducible factor (HIF) prolyl‐hydroxylases (human PHD1‐3) catalyze prolyl hydroxylation in oxygen‐dependent degradation (ODD) domains of HIFα isoforms, modifications that signal for HIFα proteasomal degradation in an oxygen‐dependent manner. PHD inhibitors are used for treatment of anemia in kidney disease. Increased erythropoietin

Cells containing aragonite crystals mediate responses to gravity in Trichoplax adhaerens (Placozoa), an animal lacking neurons and synapses. [PDF]

PLoS ONE, 2018
Trichoplax adhaerens has only six cell types. The function as well as the structure of crystal cells, the least numerous cell type, presented an enigma. Crystal cells are arrayed around the perimeter of the animal and each contains a birefringent crystal.

Defining bone fide effectors of RAS GTPases

BioEssays, Volume 45, Issue 9, September 2023., 2023
RAS GTPases transmit extracellular signals to multiple intracellular signalling pathways through direct interaction with effector proteins. These proteins typically employ RAS‐binding RBD domains to complex with activated GTPases, but the specificity of these interactions remains poorly explored and there remain few data describing the mechanistic ...

Field Biology of Placozoans (Trichoplax) [PDF]

Integrative and Comparative Biology, 2007
The goal of this review is to highlight what little is known, and point to the bulk of what is yet to be learned, about the natural history of placozoans in the field-in order to stimulate a broader search for placozoans and a fuller exploration of their distribution, diversity, and all other aspects of their enigmatic lives.

The Trichoplax genome and the nature of placozoans [PDF]

Nature, 2008
As arguably the simplest free-living animals, placozoans may represent a primitive metazoan form, yet their biology is poorly understood. Here we report the sequencing and analysis of the approximately 98 million base pair nuclear genome of the placozoan Trichoplax adhaerens.

Evolution of affinity between p53 transactivation domain and MDM2 across the animal kingdom demonstrates high plasticity of motif‐mediated interactions

Protein Science, Volume 32, Issue 7, July 2023., 2023
Abstract The interaction between the transcription factor p53 and the ubiquitin ligase MDM2 results in the degradation of p53 and is well‐studied in cancer biology and drug development. Available sequence data suggest that both p53 and MDM2‐family proteins are present across the animal kingdom.

Physiological insight into the conserved properties of Caenorhabditis elegans acid‐sensing degenerin/epithelial sodium channels

The Journal of Physiology, Volume 601, Issue 9, Page 1625-1653, 1 May 2023., 2023
Abstract figure legend Polar view of a phylogram of representative members of the DEG/ENaC superfamily, coloured according to phylum (Annelida, yellow; Arthropoda, light green; Chordata, dark green; Cnidaria, blue; Mollusca, dark purple; Nematoda, magenta; Placozoa, red). Construction of the phylogram is described in Fig. 1.

Placozoan fiber cells: mediators of innate immunity and participants in wound healing

Scientific Reports, 2021
Placozoa is a phylum of non-bilaterian marine animals. These small, flat organisms adhere to the substrate via their densely ciliated ventral epithelium, which mediates mucociliary locomotion and nutrient uptake.

Upregulation of DNA repair genes and cell extrusion underpin the remarkable radiation resistance of Trichoplax adhaerens.

PLoS Biology, 2021
Trichoplax adhaerens is the simplest multicellular animal with tissue differentiation and somatic cell turnover. Like all other multicellular organisms, it should be vulnerable to cancer, yet there have been no reports of cancer in T.
