    Tarantula toxins use common surfaces for interacting with Kv and ASIC ion channels

    Kanchan Gupta et al.
    The tarantula toxins psalmotoxin and guangxitoxin have a similar concave surface for interacting with α-helices in voltage-gated and acid-sensing ion channels.

    Structure of a pore-blocking toxin in complex with a eukaryotic voltage-dependent K+ channel

    Anirban Banerjee et al.
    Charybdotoxin, a toxin produced by scorpions, blocks a K+ channel by binding in a lock-and-key fashion to the mouth of the channel and presenting a lysine amino group, which serves as a K+ mimic in the selectivity filter.

    Bordetella adenylate cyclase toxin is a unique ligand of the integrin complement receptor 3

    Radim Osicka et al.
    A toxin produced by the bacterium Bordetella pertussis preferentially binds to non-activated integrin complement receptor 3 outside of its ligand-binding I-domain and efficiently blocks downstream signaling of the integrin through elevation of cytosolic cAMP.

    Structural insights into human acid-sensing ion channel 1a inhibition by snake toxin mambalgin1

    Demeng Sun et al.
    Mambalgin1 binds to the thumb domain of human ASIC1a channel and inhibits the channel through hindering the proton-induced transitions from the resting closed state to the active and/or desensitized state.

    An interbacterial DNA deaminase toxin directly mutagenizes surviving target populations

    Marcos H de Moraes et al.
    Interbacterial interactions can promote mutagenesis, and possibly adaptation, when intoxicated cells survive exposure to type VI secretion-delivered DNA deaminase toxins.

    Fucosylation and protein glycosylation create functional receptors for cholera toxin

    Amberlyn M Wands et al.
    Cholera intoxication of human colonic epithelial cells is dependent on recognition of protein glycosylation and fucosylation, not exclusively on ganglioside recognition as proposed previously.

    Continuous lateral oscillations as a core mechanism for taxis in Drosophila larvae

    Antoine Wystrach et al.
    Analysis of crawling Drosophila larva and agent based simulations suggest that an intrinsic rhythm rather than distinct actions underlie taxis behaviour, providing a core mechanism on which both sensory and memory pathways can converge.

    A broadly distributed toxin family mediates contact-dependent antagonism between gram-positive bacteria

    John C Whitney et al.
    Diverse LXG toxins delivered by the Esx pathway function as mediators of contact-dependent interbacterial antagonism within and between Gram-positive bacterial species.

    Structural insights into the mechanism of activation of the TRPV1 channel by a membrane-bound tarantula toxin

    Chanhyung Bae et al.
    The structure of a bivalent double-knot tarantula toxin bound to the outer pore of the capsaicin receptor reveals a novel mode of toxin-channel recognition that has important implications for thermosensation.

    Trans-toxin ion-sensitivity of charybdotoxin-blocked potassium-channels reveals unbinding transitional states

    Hans Moldenhauer et al.
    Detection of unbinding transitional states in the charybdotoxin first-order dissociation from a Kv-channel reveals that the bound neurotoxin wobbles, suggesting diverse intermediates and dissociation pathways in this protein–protein interaction.
