Radial Spokes-A Snapshot of the Motility Regulation, Assembly, and Evolution of Cilia and Flagella [PDF]
, 2016 Propulsive forces generated by cilia and flagella are used in events that are critical for the thriving of diverse eukaryotic organisms in their environments. Despite distinctive strokes and regulations, the majority of them adopt the 9+2 axoneme that is

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin
Cytoskeleton, EarlyView.ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Localized Activation of Bending in Proximal, Medial and Distal Regions of Sea-Urchin Sperm Flagella [PDF]
, 1973 Spermatozoa from the sea urchin, Colobocentrotus atratus, were partially demembranated by extraction with solutions containing Triton X-100 at a concentration which was insufficient to solubilize the membranes completely.

Cytoskeleton, EarlyView.ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

Thermodynamic Aspects of Flagellar Activity [PDF]
, 1967 1. The frequencies of the beat of cilia and flagella from various organisms have been determined at temperatures in the range 5-35°C. 2. Values of the activation enthalpy (ΔH{ddagger}, kcal./mole) and activation entropy (ΔS{ddagger}, e.u.) derived ...

Realizing the physics of motile cilia synchronization with driven colloids
, 2015 Cilia and flagella in biological systems often show large scale cooperative behaviors such as the synchronization of their beats in "metachronal waves".

, 1999 The bacterial flagellum is probably the most complex organelle found in bacteria. Although the ribosome may be made of slightly more subunits, the bacterial flagellum is a more organized and complex structure. The limited number of flagella must be targeted to the correct place on the cell membrane and a structure with cytoplasmic, cytoplasmic membrane,

An Unfolding Story: AlphaFold's View on Protein Flexibility
Helvetica Chimica Acta, EarlyView.AlphaFold confidence measures allow for detailed proteome‐wide characterization of protein flexibility. All flexibility measures increased substantially in the evolutionary transition from prokaryota to eukaryota. ABSTRACT The AlphaFold confidence measures are related to conformation distribution of the protein.

New Plant Protection, EarlyView.This review highlights how Phytophthora sojae utilizes unconventional lineage‐specific signaling networks, including unique G protein‐coupled receptor fusions, expanded kinases, and rapidly evolving effectors, to infect soybeans. Understanding these divergent molecular paradigms reveals critical vulnerabilities in this destructive pathogen, offering ...
