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.

4 GO annotations of cellular component

Name Definition
cell surface The external part of the cell wall and/or plasma membrane.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
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.
nucleolus A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.

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.

7 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.
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.
regulation of cell migration Any process that modulates the frequency, rate or extent of cell migration.
