Journal ArticleDOI
New toxins acting on sodium channels from the scorpion Leiurus quinquestriatus hebraeus suggest a clue to mammalian vs insect selectivity.
Pierre Sautière,Sandrine Cestèle,Charles Kopeyan,Arlette Martinage,Hervé Drobecq,Yvon Doljansky,Dalia Gordon +6 more
TL;DR: Two new toxins were purified from Leiurus quinquestriatus hebraeus (Lqh) scorpion venom, Lqh II and LqH III, which represent two different scorpion toxin groups, the alpha- and alpha-like toxins, respectively, according to the structural and pharmacological criteria.
Journal ArticleDOI
Phosphorylation of human sperm protamines HP1 and HP2: identification of phosphorylation sites
Frédéric Chira,Ahmed Arkhis,Arlette Martinage,Michel Jaquinod,Philippe Chevaillier,Pierre Sautière +5 more
TL;DR: Human sperm is characterized by a high heterogeneity of its basic nuclear protein complement of pro-protamines, protamines and histones, which is increased by the persistence of phosphorylated protamines in mature spermatozoa.
Journal ArticleDOI
DNA-interacting proteins in the spermiogenesis of the mollusc Murex brandaris.
Carme Càceres,Pepita Gimenez-Bonafé,Enric Ribes,Danielle Wouters-Tyrou,Arlette Martinage,Mostafa Kouach,Pierre Sautière,Sylviane Muller,Jaume Palau,Juan A. Subirana,Luis Cornudella,Manel Chiva +11 more
TL;DR: The results reveal that spermiogenic nuclear proteins are protamine precursors that are subjected to a substantial number of small N-terminal deletions that gradually modify their overall charge, promoting an efficient and extremely tight packaging of DNA.
Journal ArticleDOI
Characterization of scorpion α‐like toxin group using two new toxins from the scorpion Leiurus quinquestriatus hebraeus
Alain Hamon,Nicolas Gilles,Pierre Sautière,Arlette Martinage,Charles Kopeyan,Chris Ulens,Jan Tytgat,Jean-Marc Lancelin,Dalia Gordon +8 more
TL;DR: The structural and pharmacological properties of the new toxins are compared to those of other scorpion alpha-toxins in order to re-examine the hallmarks previously set for the alpha-like toxin group.
Journal ArticleDOI
Persistence of protamine precursors in mature sperm nuclei of the mouse
TL;DR: During mouse spermiogenesis, two protamines, mP1 and mP2, are synthesized in replacement of histones, which were previously described as the only proteins associated with DNA in sperm chromatin.
