Molecular phylogeny and evolution of the cone snails (Gastropoda, Conoidea) [PDF]

Molecular Phylogenetics and Evolution, 2014
We present a large-scale molecular phylogeny that includes 320 of the 761 recognized valid species of the cone snails (Conus), one of the most diverse groups of marine molluscs, based on three mitochondrial genes (COI, 16S rDNA and 12S rDNA). This is the first phylogeny of the taxon to employ concatenated sequences of several genes, and it includes ...

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1

British Journal of Pharmacology, EarlyView.
Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...

Diversity and Evolutionary Analysis of Venom Insulin Derived from Cone Snails

Toxins
Cone snails possess a diverse array of novel peptide toxins, which selectively target ion channels and receptors in the nervous and cardiovascular systems. These numerous novel peptide toxins are a valuable resource for future marine drug development. In

Glowing seashells: diversity of fossilized coloration patterns on coral reef-associated cone snail (Gastropoda: Conidae) shells from the Neogene of the Dominican Republic. [PDF]

PLoS ONE, 2015
The biology of modern Conidae (cone snails)--which includes the hyperdiverse genus Conus--has been intensively studied, but the fossil record of the clade remains poorly understood, particularly within an evolutionary framework.

Nicotinic acetylcholine receptor subtype expression, function, and pharmacology: Therapeutic potential of α-conotoxins

Pharmacological Research, 2023
The pentameric nicotinic acetylcholine receptors (nAChRs) are typically classed as muscle- or neuronal-type, however, the latter has also been reported in non-neuronal cells.

Distribution modelling for Neotropical freshwater stingrays Potamotrygon brachyura and Potamotrygon motoro (Myliobatiformes, Potamotrygonidae) in the Uruguay River basin

Journal of Fish Biology, EarlyView.
Abstract This study aimed to identify geographical distribution patterns of the giant short‐tailed river stingray Potamotrygon brachyura and the motoro stingray Potamotrygon motoro in the Uruguay River basin. Data on presence/absence of stingrays were based on fishers' knowledge accessed by interviews through expeditions in Brazil, Argentina and ...

Conotoxins that Confer Therapeutic Possibilities

Marine Drugs, 2012
Cone snails produce a distinctive repertoire of venom peptides that are used both as a defense mechanism and also to facilitate the immobilization and digestion of prey.

Growth and age differences between two male alternative reproductive tactics in the plainfin midshipman

Journal of Fish Biology, EarlyView.
Abstract The plainfin midshipman (Porichthys notatus Girard, 1854) is a toadfish with two distinct reproductive male tactics: ‘guarder males’ and ‘sneaker males’. These two tactics are anatomically, physiologically and behaviourally distinct from one another at sexual maturity, but it remained unclear whether these two male types remain fixed or ...
