WebJun 9, 2009 · α-crystallin, the major protein of the mammalian lens in most species, is an aggregate assembled from two polypeptides, each with a molecular weight around 20,000 Da. It is polydisperse and can be isolated in a variety of forms, including spherical particles with molecular weights ranging upwards from about 200 kDa. WebThe crystallin genes are expressed at relatively low levels in many other tissues besides lens, where they apparently function in various ways in stress amelioration; thus for example, the α-crystallin family of lens proteins is similar to the small heat shock proteins, and one of these genes responds directly to a xenobiotic response factor ... ghc wheelchair service https://scruplesandlooks.com
