Transmembrane | Unisex T-Shirt

  • Transmembrane proteins span the cell membrane and move molecules and other substances in and out of the cell. This particular structure is a CorA magnesium ion (Mg2+) transporter, common in most prokaryotes. Eukaryotes have a similar magnesium transporter. Mg2+ has a much larger structure than other molecules, such as sodium or calcium. CorA is a cation channel that is permeable to magnesium. Mg2+ is an essential nutrient for humans; adenosine triphosphate (ATP), the main source of energy in cells, needs to bind magnesium to become active.
