Wayne L. Hubbell
American biochemist
Wayne L. Hubbell (born 24 March 1943) is an American biochemist and member of the National Academy of Sciences. He is Professor of Biochemistry and Jules Stein Professor of Ophthalmology at the University of California, Los Angeles. His research focuses on the visual system, and is primarily supported by a grant from the National Eye Institute.
Research
Dr. Hubbell has studied the relationship between the molecular structure of protein and the conformational changes that control its function. Of particular interest are membrane proteins that behave as "molecular switches", i.e., proteins whose structures are switched to an active state by a physical or chemical signals. An example is light-activated rhodopsin, the visual pigment in photoreceptor cells of the retina. The goal is to elucidate the structure of rhodopsin, the mechanism of the molecular switch, and regulation of this switch by associated proteins, transducin and arrestin.
Dr. Hubbell's research also includes structure and function relationships in water-soluble proteins such as the lens protein, a-crystallin, and the retinoid carrying proteins which transport vitamin A throughout photoreceptor cells.
Begin with the source’s own compact description: “Wayne L. Hubbell” is american biochemist. The dossier treats that line as a proposition to test through Wayne, Hubbell and American, not as a finished interpretation.
Why this record matters
The phrase “american biochemist” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 31, 2026. The linked authority identifier is Q7976400. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1943.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
