Transferrin

Transferrin is a plasma protein for iron ion delivery. When a transferrin protein loaded with iron encounters a transferrin receptor on the surface of a cell, it binds to it and is consequently transported into the cell in a vesicle. The cell will acidify the vesicle, causing transferrin to release its iron ions. Each transferrin molecule has the ability to carry two iron ions in the ferric form (Fe3+). The gene coding for transferrin in humans is located in chromosome band 3q21. Transferrin ...
