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.

Organization of Dyneins in the Axoneme
2012This chapter reviews the recent progress in the understanding of axonemal dynein in the context of flagellar/ciliary bending motion. It focuses mainly on structural studies using electron microscopy/tomography but also correlates these studies with functional motility assays and theoretical studies.

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 ...

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.

DynAPs and cytoplasmic assembly of axonemal dyneins
Journal of Cell ScienceABSTRACT Motile cilia are microtubule-based organelles that generate fluid flow through coordinated beating, a process powered by axonemal dynein motors. Dyneins are pre-assembled in the cytoplasm by a suite of proteins called dynein axonemal assembly factors (DNAAFs).

Dynein heavy chain isoforms and axonemal motility
Trends in Cell Biology, 1993The translocation of dynein along microtubules is the basis for a wide variety of essential cellular movements. Dynein was first discovered in the ciliary axoneme, where it causes the directed sliding between outer doublet microtubules that underlies ciliary bending.

Axonemal dynein - a natural molecular motor
Nanotechnology, 1999Biological motor molecules possess many of the characteristics required to power nanomachines. They can generate force and torque, transport specific cargoes over appropriate substrates, and the character and rate of their action can be controlled.

AbstractIn an earlier study we reported the isolation of a cytoplasmic dynein from the cytosol of Paramecium multimicronucleatum. In this study we report the isolation and characterization of two cytosolic axonemal dyneins (22S and 12S) as well as a 19S cytoplasmic dynein from the cytosol of whole or deciliated cells using preformed bovine brain ...
