Maurocalcine is a protein isolated from the venom of the scorpion Maurus palmatus, which belongs to the family Chactidae. It was first reported by Fajloun et al. in 2000.[1]

It is 33 Amino acid residues in length, containing three disulphide bonds which folds into the inhibitor cystine knot motif.[2] It acts by modifying the activity of the type 1 ryanodine receptor.[1]
