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.

3 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
extracellular region The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
extracellular space That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

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.

10 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.
cell-cell signaling Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.
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 endothelial cell chemotaxis to fibroblast growth factor Any process that activates or increases the frequency, rate or extent of endothelial cell chemotaxis to fibroblast growth factor.
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.
response to temperature stimulus Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a temperature stimulus.
signal transduction The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
