Metallothionein-2 is a metallothionein protein that in humans is encoded by the MT2A gene.[3][4]

The single-nucleotide polymorphism rs28366003 which substitutes guanine for adenine in MT2A is associated with certain cancers and some chronic diseases.[5]

Interactions

Metallothionein 2A has been shown to interact with protein kinase D1.[6]
