Kin17_mid is the conserved central 169 residue region of a family of Kin17 proteins. Towards the N-terminal end there is a zinc-finger domain, and in human and mouse members there is a RecA-like domain further downstream. The Kin17 protein in humans forms intra-nuclear foci during cell proliferation and is re-distributed in the nucleoplasm during the cell cycle [1].
