Does not show activity on 45 human receptors from 9 families (5-hydroxytryptamine, adrenergic, dopamine, muscarinic, histamine, neurotransmitter, opioid, sigma, and gaba(A) receptors) (PubMed:27227898). In vivo, when mixed with U3-SYTX-Sth1a does not cause paralytic or lethal activity when injected into crickets (PubMed:27227898). It is noteworthy that crickets are evolutionarily distant from prey species (PubMed:27227898).<ref>PMID:27227898</ref> | ||

| + | == Publication Abstract from PubMed == | ||
| + | We present the solution-state NMR structures and preliminary functional characterizations of three venom peptides identified from the spitting spider Scytodes thoracica. Despite little sequence identity to other venom peptides, structural characterization reveals that these peptides contain an inhibitor cystine knot motif common to many venom peptides. These are the first structures for any peptide or protein from spiders of the Scytodidae family. Many venom peptides target neuronal ion channels or receptors. However, we have not been able to determine the target of these Scytodes peptides so we can only state with certainty the channels and receptors that they do not target. | ||
