GPCR - Arrestin interface interactions



The biflare plot is a modified version of a flareplot, where lines are drawn between an inner concentric circle (arrestin residues) and an outer concentric circle (GPCR residues) depicting the interface interactions.
Different interaction types are shown with different line types (aromatic - solid, hydrophobic - dashed, ionic - long dashed, polar - dotted, Van der Waals - dash-dot).
The interactive features include filtering on interaction type, segments, residues and backbone or sidechain interactions.
