Supplementary Figure 10: The interspine interaction in the crystal structure of RAC1 and RAC2.
From: Atomic structures of FUS LC domain segments reveal bases for reversible amyloid fibril formation
The crystal lattices of RAC1 (a) and RAC2 (b) are viewed down the fibril spine. One unit of fibril spine is shown in black. Tyr pointing inward the fibril spine is shown in blue. Tyr sticking outward is shown in magenta. The zoom-in views show the detailed interactions between two adjacent spines (in the yellow frames). The inter-spine π-π interaction may reflect hybrid interactions of RAC1 and RAC2 with other segments of FUS.
