WebThe photopigments that absorb light all have a similar structure, which consists of a protein called an opsin and a small attached molecule known as the chromophore. The … WebDec 13, 2002 · Melanopsin ( Opn4 ), an opsin-based photopigment, is a primary candidate for photoreceptor-mediated entrainment. To investigate the functional role of melanopsin in light resetting of the oscillator, we generated melanopsin-null mice ( Opn4 −/− ). These mice entrain to a light/dark cycle and do not exhibit any overt defect in circadian ...
