Much of our knowledge on K+-channels was elucidated using specific peptide ligands
isolated from a number of venomous organisms. Recently, this field received a strong …

Animal venoms are rich natural sources of bioactive compounds, including peptide toxins
acting on the various types of ion channels, ie K+, Na+, Cl-and Ca2+. Among K+ channel …

Four novel peptide toxins that act on voltage-gated sodium channels have been isolated
from tarantula venoms: ceratotoxins 1, 2, and 3 (CcoTx1, CcoTx2, and CcoTx3) from …

Background Scorpions like other venomous animals posses a highly specialized organ that
produces, secretes and disposes the venom components. In these animals, the last …

The diversification of the reptile venom system has been an area of major research but of
great controversy. In this review we examine the historical and modern-day efforts of all …

Background The number of protein sequences deriving from genome sequencing projects is
outpacing our knowledge about the function of these proteins. With the gap between …

Venom-derived peptide modulators of ion channel gating are regarded as essential tools for
understanding the molecular motions that occur during the opening and closing of ion …

We compared two different approaches to sequence information analysis from the
expressed sequence tag (EST) library constructed for the venom glands of the spider …

The α‐D‐phosphohexomutase superfamily is composed of four related enzymes that
catalyze a reversible, intramolecular phosphoryl transfer on their sugar substrates. The …

Venom gland transcriptomic and proteomic analyses have improved our knowledge on the
diversity of the heterogeneous components present in scorpion venoms. However, most of …
