Intermittent swimming in live sea urchin sperm
Autor: B H Gibbons
Publikováno v: The Journal of Cell Biology
Sperm of the sea urchin Tripneustes gratilla repeatedly start and stop swimming when suspended in seawater and observed by dark-field microscopy. While in the quiescent state, which usually lasts about a second, the sperm assume s shape resembling a

Organic anions stabilize the reactivated motility of sperm flagella and the latency of dynein 1 ATPase activity
Autor: B. H. Gibbons, I. R. Gibbons, Wen-Jing Y. Tang
Publikováno v: The Journal of Cell Biology
Substitution of any of a variety of organic anions, including acetate, propionate, lactate, gluconate, and succinate, for chloride in the reactivation medium improves the motility of demembranated sperm of Tripneustes gratilla. At the optimum concent

The effect of antidynein 1 serum on the movement of reactivated sea urchin sperm
Autor: B H Gibbons, I R Gibbons, K Ogawa
Publikováno v: The Journal of Cell Biology
Rabbit antiserum prepared against an ATPase-containing tryptic fragment of dynein by Ogawa and Mohri (J. Biol. Chem. 250: 6476-6483) specifically inhibited the ATPase activity of dynein 1 and not that of dynein 2. Varying amounts of this antidynein 1

Vanadate-sensitized cleavage of dynein heavy chains by 365-nm irradiation of demembranated sperm flagella and its effect on the flagellar motility
Autor: B H, Gibbons, I R, Gibbons
Publikováno v: The Journal of biological chemistry. 262(17)
Irradiation of demembranated flagella of sea urchin sperm at 365 nm in the presence of 0.05-1 mM MgATP and 5-10 microM vanadate (Vi) cleaves the alpha and beta heavy chains of the outer arm dynein at the same site and at about the same rate as report

Photosensitized cleavage of dynein heavy chains. Cleavage at the 'V1 site' by irradiation at 365 nm in the presence of ATP and vanadate
Autor: I R, Gibbons, A, Lee-Eiford, G, Mocz, C A, Phillipson, W J, Tang, B H, Gibbons
Publikováno v: The Journal of biological chemistry. 262(6)
Irradiation of soluble dynein 1 from sea urchin sperm flagella at 365 nm in the presence of MgATP and 0.05-50 microM vanadate (Vi) cleaves the alpha and beta heavy chains (Mr 428,000) at their V1 sites to give peptides of Mr 228,000 and 200,000, with

Bidirectional swimming in spermatozoa of Tephritid flies
Autor: B, Baccetti, B H, Gibbons, I R, Gibbons
Publikováno v: Journal of submicroscopic cytology and pathology. 21(4)
Our observations show that spermatozoa of the Mediterranean fruit fly Ceratitis capitata and of Dacus oleae and Dacus dorsalis are capable of swimming backwards as well as forwards, and that they can change direction abruptly. The preferred direction
