alpha B-Crystallin, a member of the small heat shock family of proteins, is synthesized as a component of various developmental programs, in response to stress and in a number of pathological states. We have determined the complete structure of the alpha B-crystallin gene (6,806 bp encompassing 2,299 bp upstream from ATG and 859 bp at the 3' end, past the(More)
alpha-Crystallin, a tissue specific structural protein of the ocular lens, is known to be composed of two subunits, alpha A and alpha B. By using a specific antibody in an immunoblotting procedure we have found that one of the subunits, alpha B is present in a number of non-lenticular tissues including the retina, heart, skeletal muscle, skin, brain, spinal(More)
The molecular cascade of stress response in higher eukaryotes commences in the cytoplasm with the trimerization of the heat shock factor 1 (HSF1), followed by its transport to the nucleus, where it binds to the heat shock element leading to the activation of transcription from the down-stream gene(s). This well-established paradigm has been mostly studied(More)
αB-crystallin (αB) is known as an intracellular Golgi membrane-associated small heat shock protein. Elevated levels of this protein have been linked with a myriad of neurodegenerative pathologies including Alzheimer disease, multiple sclerosis, and age-related macular degeneration. The membrane association of αB has been known for more than 3 decades, yet(More)

Far from being a physical entity, assembled of inanimate structural proteins, the ocular lens epitomizes the biological ingenuity that sustains an essential and near-perfect physical system of immaculate optics. Crystallins (alpha, beta, and gamma) provide transparency by dint of their high concentration, but it is debatable whether proteins that provide(More)
We have cultured and maintained human fetal lens epithelial cells for several months in primary, secondary, and tertiary culture(s). These cells show unabated synthesis of alpha B-crystallin (alpha B), a lens epithelial cell-specific marker, and progressive expression of beta Bp-crystallin (beta Bp), a major polypeptide of the differentiated lens fiber(More)
An adult lens contains two easily discernible, morphologically distinct compartments, the epithelium and the fiber-cell mass. The fiber-cell mass provides the lens with its functional phenotype, transparency. Metabolically, in comparison to the fiber cells the epithelium is the more active compartment of the ocular lens. For the purposes of this review we(More)
We have recently shown the presence of alpha B-crystallin in non-ocular tissues of diverse embryological origins such as the heart, brain, spinal cord, kidney, retina, etc. Using an alpha B-crystallin-specific antiserum and immunofluorescence, immunoblotting, immunoprecipitation and peptide mapping with Staphylococcus aureus protease, we demonstrate(More)
PURPOSE During the early phase of experimental autoimmune uveitis (EAU), before macrophages infiltrate the retina and uvea, photoreceptor mitochondrial oxidative stress, nitration of photoreceptor mitochondrial proteins, and release of cytochrome c have been observed. However, no apoptosis has been detected during this phase. In this study,(More)
