Journal ArticleDOI
Atomic-force microscopy: Rhodopsin dimers in native disc membranes
Dimitrios Fotiadis,Yan Liang,Slawomir Filipek,David A. Saperstein,Andreas Engel,Krzysztof Palczewski +5 more
TL;DR: In this article, the authors used infrared-laser atomic-force microscopy to reveal the native arrangement of rhodopsin, which forms paracrystalline arrays of dimers in mouse disc membranes.
Journal ArticleDOI
Organization of the G Protein-coupled Receptors Rhodopsin and Opsin in Native Membranes
Yan Liang,Dimitrios Fotiadis,Slawomir Filipek,David A. Saperstein,Krzysztof Palczewski,Andreas Engel +5 more
TL;DR: This is the first semi-empirical model of a higher order structure of a GPCR in native membranes, and it has profound implications for the understanding of how this receptor interacts with partner proteins.
Journal ArticleDOI
Adenoviral vector-delivered pigment epithelium-derived factor for neovascular age-related macular degeneration: results of a phase I clinical trial.
Peter A. Campochiaro,Quan Dong Nguyen,Syed Mahmood Shah,Michael L. Klein,Eric R. Holz,Robert N. Frank,David A. Saperstein,Anurag Gupta,J. Timothy Stout,Jennifer Macko,Robert DiBartolomeo,Lisa L. Wei +11 more
TL;DR: Evidence is provided that adenoviral vector-mediated ocular gene transfer is a viable approach for the treatment of ocular disorders and that further studies investigating the efficacy of AdPEDF.11 in patients with neovascular AMD should be performed.
Journal ArticleDOI
Prevalence of mutations causing retinitis pigmentosa and other inherited retinopathies
Melanie M. Sohocki,Stephen P. Daiger,Sara J. Bowne,Joseph A. Rodriquez,Hope Northrup,John R. Heckenlively,David G. Birch,Helen A. Mintz-Hittner,Richard S. Ruiz,Richard A. Lewis,David A. Saperstein,Lori S. Sullivan +11 more
TL;DR: Based on this large survey, the prevalence of disease‐causing mutations in each of these genes within specific disease categories is estimated and these data are useful in estimating the frequency of specific mutations and in selecting individuals and families for mutation‐specific studies.
Journal ArticleDOI
The G protein-coupled receptor rhodopsin in the native membrane.
Dimitrios Fotiadis,Yan Liang,Slawomir Filipek,David A. Saperstein,Andreas Engel,Krzysztof Palczewski +5 more
TL;DR: A semi‐empirical molecular model for the rhodopsin paracrystal is presented validating the previously reported results and comparing the model with other currently available models describing the supramolecular structure of GPCRs in the membrane.
