CC -!- FUNCTION: Effector cytokine of innate and adaptive immune system
CC involved in antimicrobial host defense and maintenance of tissue
CC integrity. IL17A-IL17F signals via IL17RA-IL17RC heterodimeric receptor
CC complex, triggering homotypic interaction of IL17RA and IL17RC chains
CC with TRAF3IP2 adapter through SEFIR domains. This leads to downstream
CC TRAF6-mediated activation of NF-kappa-B and MAPkinase pathways
CC ultimately resulting in transcriptional activation of cytokines,
CC chemokines, antimicrobial peptides and matrix metalloproteinases, with
CC potential strong immune inflammation. IL17A-IL17F is primarily involved
CC in host defense against extracellular bacteria and fungi by inducing
CC neutrophilic inflammation. As signature effector cytokine of T-helper
CC 17 cells (Th17), primarily induces neutrophil activation and
CC recruitment at infection and inflammatory sites. Stimulates the
CC production of antimicrobial beta-defensins DEFB1, DEFB103A, and
CC DEFB104A by mucosal epithelial cells, limiting the entry of microbes
CC through the epithelial barriers. IL17F homodimer can signal via IL17RC
CC homodimeric receptor complex, triggering downstream activation of TRAF6
CC and NF-kappa-B signaling pathway. Via IL17RC induces transcriptional
CC activation of IL33, a potent cytokine that stimulates group 2 innate
CC lymphoid cells and adaptive T-helper 2 cells involved in pulmonary
CC allergic response to fungi. Likely via IL17RC, promotes sympathetic
CC innervation of peripheral organs by coordinating the communication
CC between gamma-delta T cells and parenchymal cells. Stimulates
CC sympathetic innervation of thermogenic adipose tissue by driving TGFB1
CC expression. Regulates the composition of intestinal microbiota and
CC immune tolerance by inducing antimicrobial proteins that specifically
CC control the growth of commensal Firmicutes and Bacteroidetes.
CC {ECO:0000250|UniProtKB:Q7TNI7, ECO:0000250|UniProtKB:Q96PD4}.
CC -!- SUBUNIT: Homodimer; disulfide-linked (By similarity). Heterodimer with
CC IL17A (IL17A-IL17F) (By similarity). Forms complexes with IL17RA and
CC IL17RC receptors with 2:1 binding stoichiometry: two receptor chains
CC for one interleukin molecule. IL17F homodimer forms predominantly
CC complexes with IL17RC homodimer, whereas IL17A-IL17F favors complexes
CC with IL17RA-IL17RC. IL17RA and IL17RC chains cannot distinguish between
CC IL17A and IL17F molecules, potentially enabling the formation of
CC topologically distinct complexes (By similarity).
CC {ECO:0000250|UniProtKB:Q7TNI7, ECO:0000250|UniProtKB:Q96PD4}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q7TNI7}.
CC -!- SIMILARITY: Belongs to the IL-17 family. {ECO:0000305}.
