Interleukin 17F is a disulfide-linked homodimeric protein belonging to the IL-17 family of proinflammatory cytokines. Members belonging to this family share conserved features of cysteine-knot structures but differ in their N-terminal regions. The T-helper cell produced IL-17 family is inducible by IL15 and IL23, and IL17F induces T-cell and PBMC activation and proliferation. It also performs cartilage matrix turnover and angiogenesis prevention. Out of the IL-17 family, IL17F is the most homologous to IL17 and dimerizes in a way similar to that of nerve growth factors (NGF) and other neurotrophins.
