| Research Abstract |
A complex in which LGN associates with a partner molecule, Insc, plays a crucial role in regulating cell polarity. To elucidate the interaction between LGN and Insc based on its tertiary structure, we have been carried out structural studies of LGN-Insc compelx using by X-ray crystallography. Regions of LGN-Insc interaction as a construct suitable for structural studies were identified and then we established the preparation of the complex. We performed crystallization trials on the LGN-Insc complex and obtained crystals suitable for X-ray diffraction after optimization of crystallization condition. X-ray diffraction data were collected to a resolution of 2.8 Å for crystals of the LGN-Insc complex.
