5 GO annotations of cellular component

Name Definition
apical part of cell The region of a polarized cell that forms a tip or is distal to a base. For example, in a polarized epithelial cell, the apical region has an exposed surface and lies opposite to the basal lamina that separates the epithelium from other tissue.
cell periphery The broad region around and including the plasma membrane of a cell, encompassing the cell cortex (inside the cell), the plasma membrane, and any external encapsulating structures.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
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.

4 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
metal ion binding Binding to a metal ion.
non-membrane spanning protein tyrosine kinase activity Catalysis of the reaction
protein tyrosine kinase activity Catalysis of the reaction

23 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.
adaptive immune response An immune response mediated by cells expressing specific receptors for antigens produced through a somatic diversification process, and allowing for an enhanced secondary response to subsequent exposures to the same antigen (immunological memory).
B cell receptor signaling pathway The series of molecular signals initiated by the cross-linking of an antigen receptor on a B cell.
cellularization The separation of a multi-nucleate cell or syncytium into individual cells. An example of this is found in Drosophila melanogaster embryo development.
courtship behavior The behavior of an organism for the purpose of attracting sexual partners.
determination of adult lifespan The pathways that regulate the duration of the adult phase of the life-cycle of an animal.
DNA endoreduplication Regulated re-replication of DNA within a single cell cycle, resulting in an increased cell ploidy. An example of this process occurs in the synthesis of Drosophila salivary gland cell polytene chromosomes.
dorsal closure The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally.
female germline ring canal formation Assembly of the intercellular bridges that connect the germ-line cells of a female cyst.
head involution Movement of the anterior ectoderm to the interior of the embryo.
imaginal disc-derived male genitalia development The process whose specific outcome is the progression of the male genitalia over time, from formation as part of the genital disc to the mature structure. An example of this is found in Drosophila melanogaster.
JNK cascade An intracellular protein kinase cascade containing at least a JNK (a MAPK), a JNKK (a MAPKK) and a JUN3K (a MAP3K). The cascade can also contain an additional tier
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.
ovarian nurse cell to oocyte transport Transfer of constituents synthesized in the ovarian nurse cells to the oocyte, through the ring canals, as the egg chamber is growing. An example of this is found in Drosophila melanogaster.
peptidyl-tyrosine phosphorylation The phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine.
regulation of actin filament polymerization Any process that modulates the frequency, rate or extent of the assembly of actin filaments by the addition of actin monomers to a filament.
salivary gland morphogenesis The process in which the anatomical structures of the salivary gland are generated and organized.
sensitization An increased in a behavioral response to a repeated stimulus. For example, a shock to the tail of the marine snail Aplysia, to which the snail responds by withdrawing its gill, will result in increased gill withdrawal the next time the skin is touched.
spiracle morphogenesis, open tracheal system The process in which the anatomical structures of a spiracle are generated and organized. Spiracles are the openings in the insect open tracheal system; externally they connect to the epidermis and internally they connect to the tracheal trunk.
T cell receptor signaling pathway The series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell.
