内容記述 |
Cryptochrome (Cry) in some species could act as a quantum senser to detect the inclination angle of geomagnetic field, the function of which attributes the magnetic sensitivity of spins of unpaired electrons in radical pair (RP) in CRY generated by blue light irradiation. However, the effect of blue light on the structure and molecular behavior of Cry has not been well investigated. We conducted the size exclusion chromatography (SEC) and small-angle X-ray scattering (SAXS) analyses to inspect the molecular structure and behavior of cryptochrome 4a (ErCry4a) from European robin, a representative magnetosensory animal. The results indicated that ErCry4a could form flat-shape oligomers. Moreover, the blue light irradiation induced the contraction of ErCry4a molecule in the monomer-scale and accelerated the two-dimensional oligomerization of ErCry4a simultaneously. This oligomerization may improve the regularity for two-dimensional arrangement of ErCry4a molecules, which provides the positive effect for detecting the inclination angle. |
