The metallothioneins (MTs) are a family of small, highly conserved proteins with the specific capacity to bind metal ions. Mammalian MTs, typically 61 to 68 amino acid residues in length, with a molecular weight of 6000-7000 Daltons, contain 20 invariant cysteine residues that form two distinct metal-binding domains, without disulfide bonds, aromatic amino acids, and histidines. Metallothioneins contain two independent domains, namely α domain and β domain, both of which have independent biological functions.

Many functions of MT have been attributed to this redox-active protein, including zinc homeostasis; heavy metal detoxification; metal exchange; metal transfer; and protection against oxidative damage, inflammatory responses, and other cellular stresses.

Anti-aging & Beauty

MT has strong ability to scavenge free
radicals, about 1000 times than SOD;
MTs help skin maintaining normal function and vitality.

Wound healing

MT has a synergistic effect with cell growth
factor to promote the epithelial cells
proliferation and accelerate wound healing.

Regulation of trace elements

MT is involved in the storage,
metabolism and maintenance of trace elements
in human body; The balance of trace elements
in human body enables human tissues and
cells to play normal and orderly physiological
functions.

Anti-radiation

MT protects against ultraviolet,
ionizing radiation and the environment
damage to skin caused by pollution.

Heavy metals detoxification

MT has different affinity for different heavy
metals and reduces the content of heavy metals in human body.

Clinic treatment

MT is important for the treatment of diseases ,
such as cataracts cancer, liver disease,
inflammation, Alzheimer's disease ,etc.
