CC -!- FUNCTION: Effector cytokine of innate and adaptive immune system
CC involved in antimicrobial host defense and maintenance of tissue
CC integrity (PubMed:21350122). IL17A-IL17F signals via IL17RA-IL17RC
CC heterodimeric receptor complex, triggering homotypic interaction of
CC IL17RA and IL17RC chains with TRAF3IP2 adapter through SEFIR domains.
CC This leads to downstream TRAF6-mediated activation of NF-kappa-B and
CC MAPkinase pathways ultimately resulting in transcriptional activation
CC of cytokines, chemokines, antimicrobial peptides and matrix
CC metalloproteinases, with potential strong immune inflammation
CC (PubMed:18684971, PubMed:21350122, PubMed:11591732, PubMed:11591768,
CC PubMed:17911633, PubMed:11574464, PubMed:28827714). IL17A-IL17F is
CC primarily involved in host defense against extracellular bacteria and
CC fungi by inducing neutrophilic inflammation (By similarity). As
CC signature effector cytokine of T-helper 17 cells (Th17), primarily
CC induces neutrophil activation and recruitment at infection and
CC inflammatory sites (By similarity). Stimulates the production of
CC antimicrobial beta-defensins DEFB1, DEFB103A, and DEFB104A by mucosal
CC epithelial cells, limiting the entry of microbes through the epithelial
CC barriers (By similarity). IL17F homodimer can signal via IL17RC
CC homodimeric receptor complex, triggering downstream activation of TRAF6
CC and NF-kappa-B signaling pathway (PubMed:32187518). Via IL17RC induces
CC transcriptional activation of IL33, a potent cytokine that stimulates
CC group 2 innate lymphoid cells and adaptive T-helper 2 cells involved in
CC pulmonary allergic response to fungi. Likely via IL17RC, promotes
CC sympathetic innervation of peripheral organs by coordinating the
CC communication between gamma-delta T cells and parenchymal cells.
CC Stimulates sympathetic innervation of thermogenic adipose tissue by
CC driving TGFB1 expression (By similarity). Regulates the composition of
CC intestinal microbiota and immune tolerance by inducing antimicrobial
CC proteins that specifically control the growth of commensal Firmicutes
CC and Bacteroidetes (By similarity). {ECO:0000250|UniProtKB:Q7TNI7,

CC -!- SUBUNIT: Homodimer; disulfide-linked (PubMed:19838198,
CC PubMed:32187518). Heterodimer with IL17A (IL17A-IL17F)
CC (PubMed:17355969). Forms complexes with IL17RA and IL17RC receptors
CC with 2:1 binding stoichiometry: two receptor chains for one interleukin
CC molecule. IL17F homodimer forms predominantly complexes with IL17RC
CC homodimer, whereas IL17A-IL17F favors complexes with IL17RA-IL17RC
CC (PubMed:32187518, PubMed:28827714, PubMed:17911633, PubMed:18684971).
CC IL17RA and IL17RC chains cannot distinguish between IL17A and IL17F
CC molecules, potentially enabling the formation of topologically distinct
CC complexes (PubMed:28827714). {ECO:0000269|PubMed:17355969,

CC -!- DISEASE: Candidiasis, familial, 6 (CANDF6) [MIM:613956]: A primary

CC nails and mucous membranes caused by organisms of the genus Candida,
CC mainly Candida albicans. {ECO:0000269|PubMed:21350122}. Note=The
