Maurocalcine

Maurocalcine is an agonist of ryanodine receptor (RyR) channel types 1, 2 and 3 with cellular permeability. Maurocalcine induces [3H]ryanodine binding on RyR1 with an EC50 value of 2558 nM. Maurocalcine exhibits a apparent affinity of 14 nM for RyR2. Maurocalcine can be applied to in vivo cell tracking or other cell imaging techniques[1][2][3].
