Interaction of the synprint site of N-type Ca2+ channels with the C2B domain of synaptotagmin I.

abstract：:The 4D organization of the interphase nucleus, or the 4D Nucleome (4DN), reflects a dynamical interaction between 3D genome structure and function and its relationship to phenotype. We present initial analyses of the human 4DN, capturing genome-wide structure using chromosome conformation capture and 3D imaging, and f...
