 '''Structure of Kapβ2'''
-<scene name='Sandbox_122/Kapb2_blue/1'>KapB2</scene> is a superhelix comprised of 20 HEAT repeats (the name HEAT derives from Huntington, Elongation factor 3 A subunit of protein phosphatase 2A and Tor1 kinase), each of which consists of two anti-parallel helices. The electrostatic potential of the internal surface of Kapβ2 superhelix at the C-terminal arch is negative.

The electrostatic potential of the internal surface of Kapβ2 superhelix at the C-terminal arch is negative.
 HEAT repeats 9-13 and 14-18 form the binding site of Kapβ2 cargos while repeats 1-8 constitute the Ran GTPase binding site.3 Ran GTPase, a small 216-residue protein, is found more frequently in the nucleus and enables cargos to be released from Kapβ2.
