Biol. 5:797-806(1995). CC -!- FUNCTION: Plays an important role in the regulation of embryonic CC development, cell proliferation, cell differentiation and cell CC migration. Required for normal brain, eye, ear and limb development CC during embryogenesis. Required for normal development of the CC gonadotropin-releasing hormone (GnRH) neuronal system. Plays a role in CC neurite outgrowth in hippocampal cells (By similarity). Cooperates with CC Wnt-1 in mouse mammary tumor virus-induced murine mammary tumorigenesis CC (PubMed:7884899). {ECO:0000250|UniProtKB:P55075, CC ECO:0000269|PubMed:7884899}. CC -!- SUBUNIT: Monomer. Homodimer. Interacts with FGFR1, FGFR2, FGFR3 and CC FGFR4. Affinity between fibroblast growth factors (FGFs) and their CC receptors is increased by heparan sulfate glycosaminoglycans that CC function as coreceptors (By similarity). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=3; CC Comment=Additional isoforms seem to exist.; CC Name=FGF-8C; CC IsoId=P37237-1; Sequence=Displayed; CC Name=FGF-8B; CC IsoId=P37237-2; Sequence=VSP_001527; CC Name=FGF-8A; CC IsoId=P37237-3; Sequence=VSP_001528; CC -!- TISSUE SPECIFICITY: Absent in normal mammary glands and detected only CC in adult testis and ovary and in midgestational embryos. CC -!- INDUCTION: By androgens. CC -!- PTM: The N-terminus is blocked. CC -!- SIMILARITY: Belongs to the heparin-binding growth factors family. CC {ECO:0000305}.
