Alternative neural systems: What is a neuron? (Ctenophores, sponges and placozoans)

Frontiers in Cell and Developmental Biology, 2022
How to make a neuron, a synapse, and a neural circuit? Is there only one ‘design’ for a neural architecture with a universally shared genomic blueprint across species?

Deep RNA sequencing reveals the smallest known mitochondrial micro exon in animals: The placozoan cox1 single base pair exon. [PDF]

PLoS ONE, 2017
The phylum Placozoa holds a key position for our understanding of the evolution of mitochondrial genomes in Metazoa. Placozoans possess large mitochondrial genomes which harbor several remarkable characteristics such as a fragmented cox1 gene and trans ...

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.

Palaeobiology and taphonomy of the rangeomorph Culmofrons plumosa

Palaeontology, Volume 66, Issue 4, July/August 2023., 2023
Abstract The deep marine Ediacaran fossil record of Avalonia is dominated by the Rangeomorpha, a clade characterized by up to four orders of fractal‐like branching. Despite their abundance, morphological diversity and the recent increase in Ediacaran studies, aspects of their palaeobiology, palaeoecology and phylogenetic position in the tree of life ...

Study of NIT domain‐containing chemoreceptors from two global phytopathogens and identification of NIT domains in eukaryotes

Molecular Microbiology, Volume 119, Issue 6, Page 739-751, June 2023., 2023
NIT sensor domains were found in 19 eukaryotic and 30 bacterial phyla and formed part of 7 receptor families that generate a variety of different responses, such as chemotaxis, transcriptional regulation or homeostasis of second messenger levels.

The role of systematics for understanding ecosystem functions: Proceedings of the Zoologica Scripta Symposium, Oslo, Norway, 25 August 2022

Zoologica Scripta, Volume 52, Issue 3, Page 187-214, May 2023., 2023
Abstract On 25 August 2022, the Zoologica Scripta ‐ An International Journal of Systematic Zoology and the Norwegian Academy of Sciences and Letters arranged a symposium entitled ‘The role of systematics for understanding ecosystem functions’ in the Academy's premises in Oslo, Norway. The symposium aimed at offering a forum for exploring and discussing

Small RNAs in Cnidaria: A review

Evolutionary Applications, Volume 16, Issue 2, Page 354-364, February 2023., 2023
Abstract As fundamental components of RNA silencing, small RNA (sRNA) molecules ranging from 20 to 32 nucleotides in length have been found as potent regulators of gene expression and genome stability in many biological processes of eukaryotes. Three major small RNAs are active in animals, including the microRNA (miRNA), short interfering RNA (siRNA ...

Structure and evolution of neuronal wiring receptors and ligands

Developmental Dynamics, Volume 252, Issue 1, Page 27-60, January 2023., 2023
Abstract One of the fundamental properties of a neuronal circuit is the map of its connections. The cellular and developmental processes that allow for the growth of axons and dendrites, selection of synaptic targets, and formation of functional synapses use neuronal surface receptors and their interactions with other surface receptors, secreted ...

Evolution of factors shaping the endoplasmic reticulum

Traffic, Volume 23, Issue 9, Page 462-473, September 2022., 2022
More than 15 proteins have a role in shaping the endoplasmic reticulum (ER) but studies on the evolution of these factors are lacking. Now, a molecular evolutionary analysis indicates that reticulons, REEPs, atlastin, spastin, lunapark, TMEM33, STIM1 and VAPs likely evolved as early as the last eukaryotic common ancestor (LECA).
