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.

Structure and behaviour of the sperm terminal filament [PDF]
, 1982 Light- and electron-microscopic observations of Ciona and Lytechinus spermatozoa show a thin terminal filament at the distal end. The terminal filament is 5-6 microns long and contains the two central microtubules and a variable number of A-tubule ...

Zipping and Entanglement in Flagellar Bundle of E. Coli: Role of Motile Cell Body
, 2015 The course of a peritrichous bacterium such as E. coli crucially depends on the level of synchronization and self-organization of several rotating flagella. However, the rotation of each flagellum generates counter body movements which in turn affect the

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 ...

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.

Architecture and Assembly of Periplasmic Flagellum
Microbiology Spectrum, 2019 ABSTRACT Periplasmic flagella are complex nanomachines responsible for distinctive morphology and motility of spirochetes. Although bacterial flagella have been extensively studied for several decades in the model systems Escherichia coli and Salmonella enterica , our understanding ...

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 ...
