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.

4 GO annotations of cellular component

Name Definition
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
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.
germline ring canal Germline specific intercellular bridge. During cyst formation in insects, ring canals interconnect the cells of the cyst, facilitating the passage of cytoplasmic components between cells.
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.

32 GO annotations of biological process

Name Definition
actin cytoskeleton organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins.
adherens junction organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an adherens junction. An adherens junction is a cell-cell junction composed of the epithelial cadherin-catenin complex at which the cytoplasmic face of the plasma membrane is attached to actin filaments.
axon guidance The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.
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.
cellularization The separation of a multi-nucleate cell or syncytium into individual cells. An example of this is found in Drosophila melanogaster embryo development.
epithelial cell-cell adhesion The attachment of an epithelial cell to another epithelial cell via adhesion molecules.
female germline ring canal formation Assembly of the intercellular bridges that connect the germ-line cells of a female cyst.
female germline ring canal formation, actin assembly Recruitment and organization of actin filaments in female germline ring canals.
female germline ring canal stabilization Maintenance of the structural integrity of the ring canals connecting the female germline cyst.
filtration diaphragm assembly The aggregation, arrangement and bonding together of a set of components to form a filtration diaphragm, a specialized cell-cell junction found between the cells of the excretory system, which provides a barrier for filtration of blood or hemolymph.
germarium-derived egg chamber formation Construction of a stage-1 egg chamber in the anterior part of the germarium, from the progeny of germ-line and somatic stem cells. An example of this is found in Drosophila melanogaster.
germarium-derived female germ-line cyst encapsulation Formation of a single follicular epithelium around the germ-line derived cells of a cyst formed in the germarium. An example of this process is found in Drosophila melanogaster.
innate immune response Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
long-term memory The memory process that deals with the storage, retrieval and modification of information a long time (typically weeks, months or years) after receiving that information. This type of memory is typically dependent on gene transcription regulated by second messenger activation.
mushroom body development The process whose specific outcome is the progression of the mushroom body over time, from its formation to the mature structure. The mushroom body is composed of the prominent neuropil structures of the insect central brain, thought to be crucial for olfactory associated learning. These consist mainly of a bulbous calyx and tightly packaged arrays of thin parallel fibers of the Kenyon cells.
negative regulation of hippo signaling Any process that stops, prevents, or reduces the frequency, rate or extent of hippo signaling.
negative regulation of synaptic assembly at neuromuscular junction Any process that stops, prevents, or reduces the frequency, rate or extent of synaptic assembly at neuromuscular junction.
oocyte karyosome formation The chromosome organization process in which meiotic chromosomes in the oocyte nucleus cluster together to form a compact spherical structure called the karyosome.
oogenesis The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.
open tracheal system development The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster.
ovarian fusome organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the fusome of ovarian cells, an organelle derived from the spectrosome. It anchors the mitotic spindle pole to provide orientation during cystoblast cell divisions.
