|Protein Name||Fibroblast growth factor 1|
|Tissue Specificity||Predominantly expressed in kidney and brain. Detected at much lower levels in heart and skeletal muscle. .|
|Alternative Names||Fibroblast growth factor 1;FGF-1;Acidic fibroblast growth factor;aFGF;Endothelial cell growth factor;ECGF;Heparin-binding growth factor 1;HBGF-1;FGF1;FGFA;|
|Subcellular Localization||Secreted. Cytoplasm. Cytoplasm, cell cortex. Cytoplasm, cytosol. Nucleus. Lacks a cleavable signal sequence. Within the cytoplasm, it is transported to the cell membrane and then secreted by a non-classical pathway that requires Cu(2+) ions and S100A13. Secreted in a complex with SYT1 (By similarity). Binding of exogenous FGF1 to FGFR facilitates endocytosis followed by translocation of FGF1 across endosomal membrane into the cytosol. Nuclear import from the cytosol requires the classical nuclear import machinery, involving proteins KPNA1 and KPNB1, as well as LRRC59. .|
|Molecular Weight||17460 MW|
*if product is indicated to react with multiple species, protein info is based on the human gene.
|Protein Function||Plays an important role in the regulation of cell survival, cell division, angiogenesis, cell differentiation and cell migration. Functions as potent mitogen in vitro. .|
|Background||Fibroblast growth factor 1(acidic), also known as FGF1/ECGF/HBGF1, is a human gene which is mapped to 5q31. Human FGF1 shares 96% amino acid sequence homology with both rat and mouse. The protein encoded by this gene is a member of the fibroblast growth factor(FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is though to be involved in organogenesis. Additionally, Acidic fibroblast growth factor is derived from beta-endothelial cell growth factor(ECGFB) by posttranslational processing. Alpha-ECGF is also derived from ECGFB in the same manner.|

Guaranteed product quality
We promise all of our products perform as described in datasheets.
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
