apoferritin

 [ap″o-fer´ĭ-tin]
an apoprotein that can bind many atoms of iron per molecule to form ferritin, the form in which iron is stored in the liver and other tissues.

ap·o·fer·ri·tin

(ap'ō-fer'i-tin),
A protein in the intestinal wall that combines with a ferric hydroxide-phosphate compound to form ferritin, the first stage in the absorption of iron. Apoferritin is an oligomer of 24 chains in a spheric structure; the cavity of this sphere can contain up to 4,500 Fe3+ ions.

apoferritin

A substance with which absorbed iron may be complexed in the body to form a ferritin store. Ferritin is one of the two forms of iron store in the cells of the body. The other is haemosiderin.

To overcome these challenges, Vekilov and Yau waited for apoferritin clusters to approach the bottom of a glass cell where the researchers already had placed an apoferritin crystal as a docking point.
They found that all of these clusters had roughly the same shape--a flat layer of apoferritin molecules with a few more molecules on top.
