Alpha-crystallin A chain/CRYAA, Human (His)

Alpha-crystallin A chain/CRYAA Protein, Human (His) is a recombinant Alpha-crystallin A chain protein with a His tag. Alpha-crystallin A chain/CRYAA is a small heat shock protein and molecular chaperone that prevents nonspecific aggregation of denaturing proteins. Several point mutations in the alphaA-crystallin gene cause congenital human cataracts by unknown mechanisms[1].
