[https://www.uniprot.org/uniprot/TX90B_PHONI TX90B_PHONI] Potent blocker of nociceptor cation channels TRPA1 and high voltage-activated calcium channels (PubMed:12470700, PubMed:15933156, PubMed:27759880). It acts mainly on P/Q-type (Cav2.1/CACNA1A) calcium channels and has a minor effect on L- (Cav1/CACNA1) and N-type (Cav2.2/CACNA1B) calcium channels (PubMed:12470700, PubMed:15933156). Blocks glutamate release in synaptic transmission mediated by calcium channels (PubMed:12470700). The toxin also inhibits the KCl-induced increase of intrasynaptosomal free calcium (PubMed:12470700). It also shows antiproliferative effects on different glioma cell lines (M059J, U-138MG and U-251MG) (PubMed:28202361). In vivo, it shows analgesic effects in rodent models of pain (PubMed:18774645). In addition, it selectively blocks nocifensive responses evoked by reactive TRPA1 channel agonist (PubMed:27759880). Furthermore, it also reduces the TRPA1 channel-dependent hyperalgesia in a model of neuropathic pain induced by the chemotherapeutic agent BTZ (PubMed:27759880). In addition, it causes reduction of tumor area in the mouse glioma model, that is induced by the orthotopic injection of GL261 cells into the brain (PubMed:28202361).<ref>PMID:12470700</ref> <ref>PMID:15933156</ref> <ref>PMID:18774645</ref> <ref>PMID:28202361</ref>
