Biophysical Measurements on Axonemal Dyneins
2009In recent decades, the development of technologies such as optical trap nanometry and advanced fluorescence microscopy have provided tools for studying the dynamics of single protein molecules in vitro and in vivo with nanometer precision over timescales from milliseconds to seconds.

The Ephemeroptera sperm axoneme is devoid of outer dynein arms (ODA) and exhibits a pronounced modification of the central pair complex (CPC), which is substituted by the central sheath (CS): a tubular element of unknown molecular composition. We performed a detailed ultrastructural analysis of sperm axonemes in the genera Cloeon and Ecdyonurus using ...

Axonemal dyneins winch the cilium
Nature Structural & Molecular Biology, 2010In this issue, Ishikawa and colleagues provide direct evidence to support the 'winch' hypothesis for the dynein motor mechanism, in which the AAA domain motor unit is displaced parallel to the doublet microtubule long axis rather than undergoing a rotary motion.

Abstract Axonemal dynein forms a double row of projections, the outer and inner arms, that are attached to the A tubule of each axonemal doublet and extend toward the B tubule of the adjacent doublet.10 The outer dynein arms are distributed along the length of the A tubule, with a constant spacing of 24 nm.

Pathology of the cytoskeleton of the human sperm flagellum: axonemal and peri‐axonemal anomalies
Biology of the Cell, 1984A quantitative ultrastructural study was performed on 56 ejaculates showing anomalies of the sperm axonemal complex. The anomalies comprised either the absence of one, or more often several, axonemal structures, or defective elongation of the doublets. Several characteristics relating to the extent and superimposition of the various anomalies could be ...

Axonemal dyneins: assembly, organization, and regulation
Current Opinion in Cell Biology, 1996Progress in the sequence determination of dynein subunits is providing new insights into the locations of functional domains in these microtubule motors. Combined structural and biochemical analyses of flagellar mutations are also yielding information on the three-dimensional organization of the dynein arms and on the different components that target ...

Twist - torsion coupling in beating axonemes
AbstractMotile cilia and flagella are ubiquitous cell appendages whose regular bending waves pump fluids across tissue surfaces and enable single-cell navigation. Key to these functions are their non-planar waveforms with characteristic torsion. It is not known how torsion, a purely geometric property of the shape, is related to mechanical deformationsMartin Striegler +3 more
