FGF basic is one of at least 22 mitogenic proteins of the FGF family, which show 35 - 60% amino acid conservation.Unlike other FGFs, FGF acidic and basic lack signal peptides and are secreted by an alternate pathway. Storage pools within the cell or on cell surface heparan sulfate proteoglycans (HSPG) are likely. The predicted 18 kDa FGF basic isoform can be located in both the cytoplasm and the nucleus and is presumed to be the form secreted. Transcription from alternate start sites produces 21 - 23 kDa forms found only in the nucleus. High and low molecular weight human FGF basic targets the expression of different genes when expressed in NIH-3T3 cells.The 18 kDa rat sequence has 98% aa identity with mouse, and 96 - 97% identity with human, bovine and sheep FGF basic.
