[8] These protein were named Corona, which is the Latin word for crown, because of the crown-like shape that it forms when making contact with the surface of the cell.

Later on, the complementary DNA (cDNA) of coronin-1a was cloned in an expression library, this led to the conclusion that coronin-1a has very similar structure to the beta (β) subunits of the G proteins (Gβ).

In other words, if coronin-1a is removed and calcineurin is inhibited then it allows the initiation of the fusion of phagosomes with lysosome and the killing of mycobacteria.

The same way that coronin-1a helps with the reorganization of the cytoskeleton and dynamic activity with other proteins in vertebrates, Coronin can also be seen in non-vertebrates, for example in Toxoplasma gondii (also known as TgCor).

[11] Toxoplasma gondii coronin (TgCor) binds to F-actin and it accelerates the actin polymerization process.

As well as every other coronin, TgCor is an actin binding protein, it delocalizes to the posterior side of invading parasites and blocks them from leaving.

Model B, is the side view of the protein which shows the turns and the coils between the beta sheets.
