1 Baehr, Wolfgang; Thulin, CraigImmunolocalization and divergent roles of phosducin and phosducin-like protein in the retinaPURPOSE: These investigations were undertaken to compare and contrast the roles of phosducin and phosducin-like protein in the retina. METHODS: Phosducin and phosducin-like protein were compared in an in vitro assay measuring their inhibition of transducin binding to light-activated rhodopsin. The t...Antibody Specificity; Protein Binding; Rod Outer Segments1999
2 Frederick, Jeanne M.; Thulin, Craig; Bernstein, Paul S.Identification and characterization of a Pi isoform of glutathione S-transferase (GSTP1) as a zeaxanthin-binding protein in the macula of the human eyeUptake, metabolism, and stabilization of xanthophyll carotenoids in the retina are thought to be mediated by specific xanthophyll-binding proteins (XBPs). A membrane-associated XBP was purified from human macula using ion-exchange chromatography followed by gel-exclusion chromatography. Two-dimensio...Circular Dichroism; Isoelectric Focusing; Macula Lutea; Xanthophylls2004
