A family of small (6-7 kDa), cysteine-rich proteins that bind heavy metals with extraordinary affinity. Metallothioneins (MTs) are the cell's primary chemical defense against metal toxicity -- they sequester cadmium, mercury, lead, and other toxic metals, preventing the…
Cadmium is a toxic non-essential heavy metal (IARC Group 1 carcinogen) with a biological half-life of 17--30 years in mammals, primarily accumulating in the renal cortex via proximal tubular reabsorption of the Cd-metallothionein complex rasin 2025 cadmium exposure heal…
Cysteine is a sulfur-containing amino acid whose thiol (-SH) group makes it the primary metal-binding residue in biology. It is the rate-limiting precursor for glutathione (the master intracellular antioxidant), a key residue in metallothioneins (metal-binding proteins)…
