Figure 4.
Figure 4 The structure of IL-17F. (A) Ribbon trace of the IL-17F monomer. Strands are labeled. Disulfides are shown as ball-and-stick representation with the sulfur atoms colored yellow. Glycosylation of Asn53 is indicated by a purple ball. Inset shows a cartoon representation of the canonical cystine knot fold. Cysteine residues are indicated by filled circles; those present in IL-17 proteins are yellow, whereas the two that are missing are black. (B) Ribbon trace of the IL-17F dimer. Disulfides are shown as in (A). (C) The structure of NGF from the NGF -TrkA complex (Wiesmann et al., 1999; Protein Data Bank code 1WWW); a disordered loop connects strands 2 and 3.
