Figure 3. XKR9-SB1^XKR9 complex.

Ribbon representation of Sb1^XKR9 complexes of (A, B) full-length and (C, D) caspase-treated rXKR9. The relationship between orientations is indicated. rXKR9 is shown in unique colors, Sb1^XKR9 in gray, and the C-terminus of the full-length protein (CT) that is cleaved upon caspase-3-treatment in orange. Bound lipids are shown in green as stick models. (A, C) View is from within the membrane, with membrane boundaries indicated. (B, D) View is from the cytoplasm.

Figure 3—figure supplement 1. rXKR9-Sb1^XKR9 interactions.

(A) Ribbon representation of the rXKR9-Sb1^XKR9 interaction interface. Color code is as in Figure 3A. Secondary structure elements and complementary determining regions are indicated. (B) Stick model of interacting residues. View as in (A), with selected residues labeled.
