Descriptions
The mammalian fibroblast growth factor (FGF)1 family contains at least 22 distinct polypeptides (FGF1–FGF22) that are expressed in a specific spatial and temporal pattern. FGF9 was originally described as a glia-activating factor and is expressed in the nervous system as a potent mitogen for glia cells. FGF9 adopts a beta-trefoil fold similar to other FGFs, but the N- and C-terminal regions outside the beta-trefoil core are ordered (typical FGFs have disordered tails) and involved in reversible dimerization. Due to the dimerization, a significant surface area is buried in the dimer interface that occludes a major receptor binding site of FGF9 within the beta-trefoil core. Sequence alignment of FGFs shows that most of the residues that participate in this interface in FGF9 are conserved in FGF16, suggesting that FGF16 may also dimerize for autoinhibition.

5 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| endoplasmic reticulum | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
| extracellular space | That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. |
| Golgi apparatus | A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. |
| nucleus | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
2 GO annotations of molecular function
| Name | Definition |
|---|---|
| fibroblast growth factor receptor binding | Binding to a fibroblast growth factor receptor (FGFR). |
| growth factor activity | The function that stimulates a cell to grow or proliferate. Most growth factors have other actions besides the induction of cell growth or proliferation. |
13 GO annotations of biological process
| Name | Definition |
|---|---|
| animal organ morphogenesis | Morphogenesis of an animal organ. An organ is defined as a tissue or set of tissues that work together to perform a specific function or functions. Morphogenesis is the process in which anatomical structures are generated and organized. Organs are commonly observed as visibly distinct structures, but may also exist as loosely associated clusters of cells that work together to perform a specific function or functions. |
| cell differentiation | The cellular developmental process in which a relatively unspecialized cell, e.g. embryonic or regenerative cell, acquires specialized structural and/or functional features that characterize a specific cell. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. |
| fibroblast growth factor receptor signaling pathway | The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands. |
| organ induction | The interaction of two or more cells or tissues that causes them to change their fates and specify the development of an organ. |
| otic vesicle formation | The process resulting in the transition of the otic placode into the otic vesicle, a transient embryonic structure formed during development of the vertebrate inner ear. |
| positive regulation of cell division | Any process that activates or increases the frequency, rate or extent of cell division. |
| positive regulation of cell population proliferation | Any process that activates or increases the rate or extent of cell proliferation. |
| positive regulation of gene expression | Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA). |
| positive regulation of protein phosphorylation | Any process that activates or increases the frequency, rate or extent of addition of phosphate groups to amino acids within a protein. |
| post-anal tail morphogenesis | The process in which a post-anal tail is generated and organized. A post-anal tail is a muscular region of the body that extends posterior to the anus. The post-anal tail may aid locomotion and balance. |
| regulation of cell migration | Any process that modulates the frequency, rate or extent of cell migration. |
| semicircular canal morphogenesis | The process in which the anatomical structures of the semicircular canals are generated and organized. |
| thymus development | The process whose specific outcome is the progression of the thymus over time, from its formation to the mature structure. The thymus is a symmetric bi-lobed organ involved primarily in the differentiation of immature to mature T cells, with unique vascular, nervous, epithelial, and lymphoid cell components. |
