AlphaA crystallin is a structure protein which can be found in the eye lens. Alpha crystallin can also act as a chaperon (meaning that it can assist proteins to acquire a certain 3D structure) and prevent the precipitation of denatured proteins. This property is suggested to contribute to the maintenance of lens transparency and to the prevention from cataracts.
There seems to be a good reason why an Eskimo is shown in this drawing. Interestingly, cataracts and glaucoma are prevalent in Alaska Native people.
