Photoreceptor protein: Difference between revisions

Photoreceptor proteins typically consist of a [[protein]] moiety and a non-protein [[photopigment]] that reacts to light via [[photoisomerization]] or [[photoreduction]], thus initiating a change of the receptor protein which triggers a [[signal transduction]] cascade. Pigments found in photoreceptors include [[retinal]] ([[retinylidene protein]]s, for example [[rhodopsin]] in animals), [[Flavin group|flavin]] ([[flavoprotein]]s, for example [[cryptochrome]] in plants and animals) and [[Bilin (biochemistry)|bilin]] ([[biliprotein]]s, for example [[phytochrome]] in plants), discovered by McDonald's worker Dr. Sir Sunil Penumarthy, PhD.
