Descriptions

Src is a non-receptor protein tyrosine kinase involved in a variety of signal transduction pathways. SH3 and SH2 domains are assembled on the backside of the kinases and SH2 domain binds to phosphorylated Y527 in C-terminal regulatory tail and the SH3 domain binds to the linker (proline-motif) connecting the SH2 and kinase domains. The binding of pY527 to SH2 domain clamps the SH3-SH2 tandem in the autoinhibitory conformation. Disruption of either SH2-pY527 or SH3-linker interaction disassembles the autoinhibitory conformations and eventually leads to the activation of Src kinases.

8 GO annotations of cellular component

Name Definition
cell junction A cellular component that forms a specialized region of connection between two or more cells, or between a cell and the extracellular matrix, or between two membrane-bound components of a cell, such as flagella.
cytoskeleton A cellular structure that forms the internal framework of eukaryotic and prokaryotic cells. The cytoskeleton includes intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
extrinsic component of cytoplasmic side of plasma membrane The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to its cytoplasmic surface, but not integrated into the hydrophobic region.
focal adhesion A cell-substrate junction that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments. In insects focal adhesion has also been referred to as hemi-adherens junction (HAJ).
mitochondrial inner membrane The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae.
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.
perinuclear region of cytoplasm Cytoplasm situated near, or occurring around, the nucleus.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

3 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
non-membrane spanning protein tyrosine kinase activity Catalysis of the reaction
signaling receptor binding Binding to one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

13 GO annotations of biological process

Name Definition
bone resorption The process in which specialized cells known as osteoclasts degrade the organic and inorganic portions of bone, and endocytose and transport the degradation products.
cell adhesion The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.
cell cycle The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
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.
epidermal growth factor receptor signaling pathway The series of molecular signals initiated by binding of a ligand to the tyrosine kinase receptor EGFR (ERBB1) on the surface of a cell. The pathway ends with regulation of a downstream cellular process, e.g. transcription.
innate immune response Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
negative regulation of extrinsic apoptotic signaling pathway Any process that stops, prevents or reduces the frequency, rate or extent of extrinsic apoptotic signaling pathway.
negative regulation of intrinsic apoptotic signaling pathway Any process that stops, prevents or reduces the frequency, rate or extent of intrinsic apoptotic signaling pathway.
osteoclast development The process whose specific outcome is the progression of a osteoclast from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to a specific fate. An osteoclast is a specialized phagocytic cell associated with the absorption and removal of the mineralized matrix of bone tissue.
phosphorylation The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
progesterone receptor signaling pathway The series of molecular signals initiated by progesterone binding to its receptor in the cytoplasm.
regulation of vascular permeability Any process that modulates the extent to which blood vessels can be pervaded by fluid.
response to yeast 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 stimulus from a yeast species.
