Correction: In Vivo Substrates of the Lens Molecular Chaperones αA-Crystallin and αB-Crystallin
αA-crystallin and αB-crystallin are members of the small heat shock protein family and function as molecular chaperones and major lens structural proteins. Although numerous studies have examined their chaperone-like activities in vitro, little is known about the proteins they protect in vivo. To elucidate the relationships between chaperone function, substrate binding, and human cataract forma...
متن کاملαA-crystallin and αB-crystallin reside in separate subcellular compartments in the developing ocular lens.
αA-Crystallin (αA) and αB-crystallin (αB), the two prominent members of the small heat shock family of proteins are considered to be two subunits of one multimeric protein, α-crystallin, within the ocular lens. Outside of the ocular lens, however, αA and αB are known to be two independent proteins, with mutually exclusive expression in many tissues. This dichotomous view is buoyed by the high e...
متن کاملAnalysis of non-crystallin lens fiber cell gene expression in c-Maf -/- mice.
PURPOSE To examine the role of the c-Maf transcription factor in the regulation of non-crystallin lens fiber cell specific gene expression. METHODS Expression of lens fiber cell genes in c-Maf null mice was analyzed by immunohistochemical and RT-PCR methods. In addition, the effect of c-Maf on fiber cell gene promoter fragments was examined in co-transfection experiments. RESULTS Examinatio...
متن کاملCell penetration peptides for enhanced entry of αB-crystallin into lens cells.
PURPOSE The prevalence of cataract increases with age. Conversely, the abundance of native α-crystallin diminishes with age and cataract development. We hypothesize replenishing lens α-crystallin may delay or prevent cataract. Herein we investigated the ability of cell penetration peptides (CPP) to enhance entry of α-crystallins into lens-derived cells. METHODS Recombinant αB-crystallins were...
متن کاملPrenatal lens development in connexin43 and connexin50 double knockout mice.
PURPOSE To determine the roles of intercellular communication in embryonic eye growth and development, mice with a targeted deletion of the Cx43 gene were examined, and mice without both Cx43 and Cx50 were generated and analyzed. METHODS Embryonic eyes and lenses from wild-type mice, or mice deficient in Cx43, Cx50, or both Cx43 and Cx50 were collected and analyzed structurally by light and e...
