However, it is unclear where and how the clCry4 receives the magnetic information and transmits it to perception. The Fe-S cluster assembly 1 homolog clISCA1, which interacts with clCry4, is one of the candidates that may assist the magnetic response and/or the signal transduction of Cry. By SAXS analysis, we revealed that the native structure of clISCA1 is changeable between the globular and the rod-like shapes. This structural change affects the affinity of clISCA1 for Fe-S cluster, and consequently the magnetoreception reaction of the clCry4/clISCA1 complex might be controlled. In this symposium, we introduce our research and the overview of this research field., 第58回日本生物物理学会年会(BSJ2020)}, title = {Molecular behavior of the second magnetorecepter candidate protein ISCA1}, year = {2020} }
