1965 Gibbons & Rowe in Science 23 July 424/2 We propose the term ‘dynein’ (dyne, force; -in, protein) to describe..adenosine triphosphatase proteins associated with motile structures.
1974 Sci. Amer. Oct. 50/2 If the ciliary microtubules could ‘walk along’ one another by means of their dynein arms, one could envisage that, given the right sequence of activity and appropriate shear resistance with the axoneme, bends would form.
1979 Nature 7 June 532/1 The force required for motion of cilia, eukaryotic flagella and sperm tails is generated by the dynein arms... The dynein arms have been shown to contain Mg2+ -ATPases.
1985 Sci. Amer. Oct. 99/1 In cilia and flagella tubulin links with a flexible protein known as dynein.
