On The Cover: A ribbon illustration shows the polar core (red sticks and spheres) within the transmembrane domains of human glucagon receptor (gray) in complex with the glucagon receptor antagonist MK-0893 (green). The polar core, which is locked in the inactive conformation by the antagonist, is composed of conserved residues from TM2, TM3, TM6, and TM7, and mutations in this conserved polar core lead to constitutive activation of the glucagon receptors. The cover figure was prepared by Yanting Yin.
