Journal ArticleDOI

Atomic-force microscopy: Rhodopsin dimers in native disc membranes

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

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

Prevalence of mutations causing retinitis pigmentosa and other inherited retinopathies

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.

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.
