Alpha B Crystallin, first identified as a structural component of the vertebrate eye lens, is expressed at high levels in lens and at lower levels in a number of other tissues, most notably cardiac and skeletal muscle, kidney, and brain (1). It is a major protein component of Rosenthal fibers (RF), which massively accumulate in the brains of patients suffering from Alexander's disease (2). The major phosphorylation site of Alpha B Crystallin in brains of patients with Alexander's disease or Alzheimer's disease as well as in aged controls is Serine 59 (3). Racemization, isomerization, and oxidation of Alpha B Crystallin are said to occur spontaneously in the aging process (4).
