Global diversity of the Placozoa.
The enigmatic animal phylum Placozoa holds a key position in the metazoan Tree of Life. A simple bauplan makes it appear to be the most basal metazoan known and genetic evidence also points to a position close to the last common metazoan ancestor ...

Beyond the Secretory Pathway: New Insights Into Protein Release
While proteins bearing N‐terminal signal or leader sequences are secreted via the ER‐Golgi‐plasma membrane axis of the conventional secretion pathway, many cytosolic proteins lacking signaling sequence can be secreted via poorly defined mechanisms termed Unconventional Protein Secretion (UcPS).

After having been largely neglected for more than a century, the tiny marine animal Trichoplax adhaerens is enjoying a revival and is now poised to become a mainstream model organism for the study of epithelial evolution, diversification and specialization.

Concatenated analysis sheds light on early metazoan evolution and fuels a modern "urmetazoon" hypothesis. [PDF]
For more than a century, the origin of metazoan animals has been debated. One aspect of this debate has been centered on what the hypothetical "urmetazoon" bauplan might have been.

Invertebrate Bile Acid‐Sensitive Ion Channels and Their Emergence in Bilateria
This graphical abstract presents the evolutionary distribution and functional characteristics of bile acid‐sensing ion channels (BASICs) across bilaterians. A phylogenetic tree illustrates the presence of BASICs in diverse groups, extending beyond previously established mammalian findings.

Domain‐Shuffling in the Evolution of Cyclostomes and Gnathostomes
We addressed the potential roles of domain‐shuffling origin genes (DSO‐Gs) in the evolution of early vertebrates. Through comparative genome analysis of 22 metazoans, including four cyclostomes, we identified DSO‐Gs before and after the divergence of cyclostomes and gnathostomes, and suggest domain shuffling as a key mechanism in vertebrate early ...

Studying Placozoa WBR in the Simplest Metazoan Animal, Trichoplax adhaerens
AbstractPlacozoans are a promising model system to study fundamental regeneration processes in a morphologically and genetically very simple animal. We here provide a brief introduction to the enigmatic Placozoa and summarize the state of the art of animal handling and experimental manipulation possibilities.

Developmental gene expression in the eyes of the pygmy squid Xipholeptos notoides
In the cephalopod Xipholeptos notoides, the photosensitive pigment encoding genes Rhodopsin, Xenopsin, and Retinochrome, as well as two Reflectin genes are expressed in the olfactory organ. This suggests that either opsins may not only be involved in photoreception or the olfactory organ is involved in photoreception.

Evolution of the Cdk4/6–Cdkn2 system in invertebrates
Hypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.

The origin and evolution of G protein-coupled receptor kinases. [PDF]
G protein-coupled receptor (GPCR) kinases (GRKs) play key role in homologous desensitization of GPCRs. GRKs phosphorylate activated receptors, promoting high affinity binding of arrestins, which precludes G protein coupling.
