Ultrastructure of the sperm axoneme and molecular analysis of axonemal dynein in ephemeroptera (Insecta)

Cytoskeleton, 2014
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

Current Opinion in Cell Biology, 1992
Recent advances in our understanding of the axonemal dyneins reveal them to be much more complex than previously believed. A combination of genetic, molecular genetic, ultrastructural and biochemical approaches is now aiding the elucidation of the organization and function of these important mechanochemical transducers.

Axonemal motility in Chlamydomonas

2015
Motile cilia and flagella rapidly propagate bending waves and produce water flow over the cell surface. Their function is important for the physiology and development of various organisms including humans. The movement is based on the sliding between outer doublet microtubules driven by axonemal dyneins, and is regulated by various axonemal components ...

Pathology of the cytoskeleton of the human sperm flagellum: axonemal and peri‐axonemal anomalies

Biology of the Cell, 1984
A 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 ...

Unusual Axonemes of Hexapod Spermatozoa

2006
Hexapod spermatozoa exhibit a great variation in their axoneme structure. The 9+2 pattern organization is present in a few basal taxa and in some derived groups. In most hexapods, a crown of nine accessory microtubules surrounds the 9+2 array, giving rise to the so-called 9+9+2 pattern.

Axonemal dynein from Tetrahymena

Journal of Cell Science, 1991
ABSTRACT Axonemal dynein from Tetrahymena cilia can be separated on a sucrose gradient into two fractions, at least one of which appears to be polymorphic. We have been using immuno-electron microscopy in order to try and locate the different types of dynein molecules within the axonemal structure.

Posttranslational Modifications of Axonemal Tubulin

Journal of Protein Chemistry, 1997
Axonemal tubulin exhibits a high degree of heterogeneity mostly due to several posttranslational modifications (PTM). The aim of this work was to chemically characterize the different PTM occurring in the C-terminal tail of axonemal tubulin purified from sea urchin, Paracentrotus lividus, spermatozoa.

Physical model of axonemal splitting

Cell Motility, 1994
AbstractA physical model developed to explain microtubule sliding patterns in the trypsintreated ciliary axoneme has been extended to investigate the generation of bending moments by microtubules sliding in an axoneme in which the dublets are anchored at one end.

22S axonemal dynein is preassembled and functional prior to being transported to and attached on the axonemes

Cell Motility, 1994
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 ...
