Essential Role of CFAP53 in Sperm Flagellum Biogenesis
Frontiers in Cell and Developmental Biology, 2021 The sperm flagellum is essential for male fertility. Despite vigorous research progress toward understanding the pathogenesis of flagellum-related diseases, much remains unknown about the mechanisms underlying the flagellum biogenesis itself.

The optimal elastic flagellum [PDF]
Phys. Fluids (2010) 22, 031901, 2009 Motile eukaryotic cells propel themselves in viscous fluids by passing waves of bending deformation down their flagella. An infinitely long flagellum achieves a hydrodynamically optimal low-Reynolds number locomotion when the angle between its local tangent and the swimming direction remains constant along its length.

Mechanics of a Flagellum [PDF]
Nature, 1941 CONSIDER a simple homogeneous filament with a wave passing in the direction indicated and suppose that the filament is immersed in water (a). Allow also that the wave is passing along the filament with both an increase in velocity and amplitude and hence an increase in resistance from the water.

Assembly and Dynamics of the Bacterial Flagellum.
Annual Review of Microbiology, 2020 The bacterial flagellar motor is the most complex structure in the bacterial cell, driving the ion-driven rotation of the helical flagellum. The ordered expression of the regulon and the assembly of the series of interacting protein rings, spanning the ...

An orphan kinesin controls trypanosome morphology transitions by targeting FLAM3 to the flagellum.
PLoS Pathogens, 2018 Trypanosoma brucei undergoes life cycle form transitions from trypomastigotes to epimastigotes in the insect vector by re-positioning the mitochondrial genome and re-locating the flagellum and flagellum-associated cytoskeletal structures.

The Flagellum of Trypanosomes [PDF]
, 2005 Eukaryotic cilia and flagella are cytoskeletal organelles that are remarkably conserved from protists to mammals. Their basic unit is the axoneme, a well-defined cylindrical structure composed of microtubules and up to 250 associated proteins. These complex organelles are assembled by a dynamic process called intraflagellar transport.

A Flagellum-specific Calcium Sensor [PDF]
Journal of Biological Chemistry, 2005 The flagellar calcium-binding protein (FCaBP) of the flagellated protozoan Trypanosoma cruzi associates with the flagellar membrane via its N-terminal myristate and palmitate moieties in a calcium-modulated, conformation-dependent manner. This mechanism of localization is similar to that described for neuronal calcium sensors, which undergo calcium ...

The Role of the Bacterial Flagellum in Adhesion and Virulence
Biology, 2013 The bacterial flagellum is a complex apparatus assembled of more than 20 different proteins. The flagellar basal body traverses the cell wall, whereas the curved hook connects the basal body to the whip-like flagellar filament that protrudes several µm ...

Ccdc38 is required for sperm flagellum biogenesis and male fertility in mice.
Development, 2022 The sperm flagellum is essential for male fertility, and defects in flagellum biogenesis are associated with male infertility. Deficiency of CCDC42 is specifically associated with malformation of mouse sperm flagella.
