Actions biochimiques/physiologiques

Margatoxin is an α-KTx toxin, which is majorly used in ion channel research. It is a 39-amino acid peptide, which is a specific K(V)1.3 channel voltage-dependent K⁺channel blocker. Margatoxin is an immunosuppressant that is isolated from the venom of the scorpion Centruroides margaritatus.

The effects of Kv1.3 and IKCa1 potassium channel inhibition on calcium influx of human peripheral T lymphocytes in rheumatoid arthritis.

Gergely Toldi et al.

Immunobiology, 218(3), 311-316 (2012-06-19)

The transient increase of the cytoplasmic free calcium level plays a key role in the process of lymphocyte activation. Kv1.3 and IKCa1 potassium channels are important regulators of the maintenance of calcium influx during lymphocyte activation and present a possible

Purification, characterization, and biosynthesis of margatoxin, a component of Centruroides margaritatus venom that selectively inhibits voltage-dependent potassium channels.

M Garcia-Calvo et al.

The Journal of biological chemistry, 268(25), 18866-18874 (1993-09-05)

A novel peptidyl inhibitor of K+ channels has been purified to homogeneity from venom of the new world scorpion Centruroides margaritatus. The primary structure of this 39-amino-acid peptide, which we term margatoxin (MgTX), was determined by amino acid compositional analysis

Margatoxin is a non-selective inhibitor of human Kv1.3 K+ channels.

Suppressing Kv1.3 Ion Channel Activity with a Novel Small Molecule Inhibitor Ameliorates Inflammation in a Humanised Mouse Model of Ulcerative Colitis.

Anna-Lena Unterweger et al.

Journal of Crohn's & colitis, 15(11), 1943-1958 (2021-04-24)

The potassium channel Kv1.3 is a potentially attractive therapeutic target in T cell-mediated inflammatory diseases, as the activity of antigen-activated T cells is selectively impeded by Kv1.3 inhibition. In this study, we examined Kv1.3 as a potential therapeutic intervention point

Potassium channels in rat prostate epithelial cells.

H Ouadid-Ahidouch et al.

FEBS letters, 459(1), 15-21 (1999-10-06)

Voltage-dependent K(+) channels were identified and characterized in primary culture of rat prostate epithelial cells. A voltage-dependent, inactivating K(+) channel was the most commonly observed ion channel in both lateral and dorsal cells. The K(+) current exhibited a voltage threshold
