This study identifies two distinct core minor pilin complexes in cyanobacteria that prime specialized Type IV filaments for natural competence and motility.

This study identifies a PP2A regulatory network in Sulfolobus acidocaldarius that controls surface structures and motility through phosphorylation-dependent signaling.

This paper identifies a three-protein system in Archaea essential for divisome positioning, showing functional similarities to the bacterial Min system but with distinct sequence and mechanism.

The paper identifies and classifies archaeal TFF systems using MacSyFinder2, revealing their diversity and functional expansion through structural and genomic analyses.

This study identifies three high affinity G-actin binding sites in YAP and shows that actin binding is necessary for YAP's transcriptional activity and function.

This study identifies CsmR as a transcriptional regulator linking motility and cell shape in Haloferax volcanii through transcriptomic analysis and functional experiments.

This study examines the growth, morphology, and surface appendages of Litorilinea aerophila, revealing unique features of its cell envelope and multicellular organization.

The paper shows that archaellum gene clusters, which enable motility, are present in bacteria and originated from horizontal gene transfer from archaea.

The paper identifies two novel components, UpsC and CedD, involved in DNA repair mechanisms in Sulfolobus acidocaldarius through genetic analysis and functional assays.

The paper identifies a contact-dependent antagonism mechanism in archaea mediated by a CIS similar to bacterial T6SSs, revealing its role in shaping microbial communities.

This study shows that MinD2 in Haloferax volcanii affects cell shape and motility by mispositioning chemotaxis arrays and archaellum motors, and interacts synergistically with MinD4.
