Biochem/physiol Actions
Toxin found in the venom of the funnel web spider, Agelenopsis aptera. Potent, selective P-type and Q-type calcium-channel blocker, without effect on L-type, N-type, or T-type calcium channels. Used to differentiate the types of calcium channel active during various physiological processes

The primary sensory Rohon-Beard (R-B) neurons of Xenopus larvae are highly analogous to the C fibers of the mammalian pain pathway. We explored the actions of 5-HT by studying the modulation of Ca2+ currents. In approximately 80% of the acutely

The sympathetic preganglionic nerve terminals of the rat superior cervical ganglion were loaded with the calcium indicator oregon green 488 BAPTA-1 to measure the change in calcium concentration in the terminal boutons, (delta[Ca2+]b) following short (1 or 5 impulses) and

In the course of purification of omega-Aga-IVA, a specific P-type calcium channel blocker, from the venom of Agelenopsis aperta we discovered a novel peptide. This peptide, named omega-agatoxin Tsukuba (omega-Aga-TK), also blocked P-type channels and was twelve times more abundant

We characterized the electrophysiological properties of calcium channels in cultured rat hippocampal neurones using omega-agatoxin-TK (omega-Aga-TK) and compared them with those of the P-type channel and the BI (alpha 1A) channel which resembles the Q-type channel. Two types of omega-Aga-TK-sensitive

We characterized the electrophysiological properties of calcium channels in cultured rat cerebral cortical neurons using omega-agatoxin-TK (omega-Aga-TK) by a patch-clamp technique. Two types of slowly inactivating calcium channels sensitive to omega-Aga-TK were detected. The first type showed high sensitivity to
