Olivera, Baldomero M. | Block of Shaker K+ channels by ĸ-conotoxin PVIIA is state dependent | ĸ-conotoxin PVIIA is the first conotoxin known to interact with voltage-gated potassium channels by inhibiting Shaker-mediated currents. We studied the mechanism of inhibition and concluded that PVIIA blocks the ion pore with a 1:1 stoichiometry and that binding to open or closed channels is very d... | Conotoxins; k-conotoxin PVIIA; Potassium channel blockers; Shaker K+ channels | 1999 |

Olivera, Baldomero M. | ?O-Conotoxins inhibit NaV channels by interfering with their voltage sensors in domain-2 | The ?O-conotoxins MrVIA and MrVIB are 31-residue peptides from Conus marmoreus, belonging to the O-superfamily of conotoxins with three disulfide bridges. They have attracted attention because they are inhibitors of tetrodotoxin-insensitive voltage-gated sodium channels (NaV1.8) and could therefore ... | 2007 | |

Yamaguchi, Ayako | Coding rate and duration of vocalizations of the frog , Xenopus laevis | Vocalizations involve complex rhythmic motor patterns, but the underlying temporal coding mechanisms in the nervous system are poorly understood. Using a recently developed whole-brain preparation from which "fictive" vocalizations are readily elicited in vitro, we investigated the cellular basis of... | 2012-08-29 | |

Pascucci, Valerio | Computing morse-smale complexes with accurate geometry | Topological techniques have proven highly successful in analyzing and visualizing scientific data. As a result, significant efforts have been made to compute structures like the Morse-Smale complex as robustly and efficiently as possible.

Olivera, Baldomero M. | Combined proteomic and transcriptomic interrogation of the venom gland of conus geographus uncovers novel components and functional compartmentalization | Cone snails are highly successful marine predators that use complex venoms to capture prey. At any given time, hundreds of toxins (conotoxins) are synthesized in the secretory epithelial cells of the venom gland, a long and convoluted organ that can measure 4 times the length of the snail's body. In... | 2014-01-01 | |
