Mad28, a conserved actin-like protein in deep-branching magnetotactic bacteria, exhibits cell curvature-dependent localization [PDF]

Journal of Bacteriology
Magnetotactic bacteria (MTB) synthesize magnetic bacterial organelles called magnetosomes, which enable them to navigate along the geomagnetic field in aquatic environments.

Dynamic Filament Formation by a Divergent Bacterial Actin-Like ParM Protein. [PDF]

PLoS ONE, 2016
Actin-like proteins (Alps) are a diverse family of proteins whose genes are abundant in the chromosomes and mobile genetic elements of many bacteria.

NEK7 phosphorylation of cortactin modulates the migratory capacity of cells expressing EML4-ALK V3 [PDF]

Scientific Reports
EML4-ALK is a common oncogenic driver of non-small cell lung cancer. Distinct EML4-ALK variants cause different rates of disease progression, with patients expressing variant 3 (V3) exhibiting accelerated metastasis.

Alp7R regulates expression of the actin-like protein Alp7A in Bacillus subtilis. [PDF]

J Bacteriol, 2012
Alp7A is a bacterial actin from Bacillus subtilis plasmid pLS20 that functions in plasmid segregation. Alp7A's function requires that it assemble into filaments that treadmill and exhibit dynamic instability. These dynamic properties require the two other components of the alp7A operon, the downstream alp7R gene and the upstream alp7C sequence, as does

Reconstitution of the transition from a lamellipodia- to filopodia-like actin network with purified proteins

European Journal of Cell Biology, 2023
How cells utilize complex mixtures of actin binding proteins to assemble and maintain functionally diverse actin filament networks with distinct architectures and dynamics within a common cytoplasm is a longstanding question in cell biology. A compelling

LUZP1: A new player in the actin-microtubule cross-talk

European Journal of Cell Biology, 2022
LUZP1 (leucine zipper protein 1) was first described as being important for embryonic development. Luzp1 null mice present defective neural tube closure and cardiovascular problems, which cause perinatal death.

Actin capping protein regulates postsynaptic spine development through CPI-motif interactions

Frontiers in Molecular Neuroscience, 2022
Dendritic spines are small actin-rich protrusions essential for the formation of functional circuits in the mammalian brain. During development, spines begin as dynamic filopodia-like protrusions that are then replaced by relatively stable spines ...

Indications for a genetic basis for big bacteria and description of the giant cable bacterium Candidatus Electrothrix gigas sp. nov.

Microbiology Spectrum, 2023
Bacterial cells can vary greatly in size, from a few hundred nanometers to hundreds of micrometers in diameter. Filamentous cable bacteria also display substantial size differences, with filament diameters ranging from 0.4 to 8 µm.

EhCoactosin stabilizes actin filaments in the protist parasite Entamoeba histolytica. [PDF]

PLoS Pathogens, 2014
Entamoeba histolytica is a protist parasite that is the causative agent of amoebiasis, and is a highly motile organism. The motility is essential for its survival and pathogenesis, and a dynamic actin cytoskeleton is required for this process ...

Dynamic movement of actin‐like proteins within bacterial cells [PDF]

EMBO reports, 2004
Actin proteins are present in pro‐ and eukaryotes, and have been shown to perform motor‐like functions in eukaryotic cells in a variety of processes. Bacterial actin homologues are essential for cell viability and have been implicated in the formation of rod cell shape, as well as in segregation of plasmids and whole chromosomes.
