FGF-12: ProductsFGF-12 is a member of the FGF superfamily of heparin-binding mitogenic molecules characterized by the presence of a core, 120 amino acid (aa) beta-trefoil structure. FGF-11, -12, -13, -14, originally termed FGF homologous factors (FHF) -3, -1, -2, and -4, respectively, form a subgroup within the FGF family. Human FGF-12/FHF-1 is synthesized as a 243 aa protein. It lacks a typical signal sequence and is considered cytoplasmic. It also possess an N-terminal bipartite nuclear localization signal at aa 11-18 and 28-38.
