Human borealin N-terminal (green) complex with survivin (deepskyblue), INCENP N-terminal (pink), MES and Zn+2 ion (grey) (PDB code 2qfa) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function Borealin (BOR) is a member of the chromosomal passenger complex (CPC) which includes survivin and INCENP. It is required for the stability of the bipolar mitotic spindle[1]. Relevance Borealin plays a key role in liver development, regeneration and tumorigenesis and may be a potential target for related liver diseases[2]. Structural highlights The interactions between BOR, survivin and INCENP involve a set of hydrophobic interactions formed by the three-helix bundle and links by [3].
