WebHuman γD-Crystallin Structure and Function. The human γD-crystallin (HγD) is the second most abundant protein of the lens nucleus (Ji 2013), and it is believed that their main function is to help maintaining the optical properties of the lens during the life span. Consequently, the γD-crystallins have evolved to be stable, soluble at ... WebCytoskeletal proteins comprise less than 10% of the total protein the human lens but their function as an intracellular lattice may be very important for the early stages of differentiation when the concentration of crystallin proteins increases most rapidly (Matsushima et al., 1997).

WebJan 29, 2024 · The findings of the researchers suggest that alpha-A crystallin plays an active role in protecting other proteins from oxidation. It was found that oxidized alpha-A crystallin can even transfer the disulfide bridge present to other proteins and thereby influence the redox state of other lens proteins. WebTwo additional functions of alpha crystallins are an autokinase activity and participation in the intracellular architecture. The encoded protein has been identified as a moonlighting … The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. However, this is not their only function. It has become clear that crystallins may have several metabolic and regulatory functions, both within the lens and in other parts of the … See more In anatomy, a crystallin is a water-soluble structural protein found in the lens and the cornea of the eye accounting for the transparency of the structure.
