EOG8W6R90 GO:0007099 4/81 centriole replication biological_process "The cell cycle process in which a daughter centriole is formed perpendicular to an existing centriole. An immature centriole contains a ninefold radially symmetric array of single microtubules; mature centrioles consist of a radial array of nine microtubule triplets, doublets, or singlets depending upon the species and cell type." [GOC:kmv, ISBN:0815316194] EOG8W6R90 GO:0010457 3/81 centriole-centriole cohesion biological_process "The process in which the two centrioles within a centrosome remain tightly paired." [GOC:dph, GOC:tb] EOG8W6R90 GO:0005813 1/81 centrosome cellular_component "A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle." [GOC:mah, ISBN:0198547684] EOG8W6R90 GO:0007026 1/81 negative regulation of microtubule depolymerization biological_process "Any process that stops, prevents, or reduces the frequency, rate or extent of microtubule depolymerization; prevention of depolymerization of a microtubule can result from binding by 'capping' at the plus end (e.g. by interaction with another cellular protein of structure) or by exposing microtubules to a stabilizing drug such as taxol." [GOC:mah, ISBN:0815316194] EOG8W6R90 GO:0007288 1/81 sperm axoneme assembly biological_process "The assembly and organization of the sperm flagellar axoneme, the bundle of microtubules and associated proteins that forms the core of the eukaryotic sperm flagellum, and is responsible for movement." [GOC:bf, ISBN:0198547684] EOG8W6R90 GO:0008017 1/81 microtubule binding molecular_function "Interacting selectively and non-covalently with microtubules, filaments composed of tubulin monomers." [GOC:krc] EOG8W6R90 GO:0051297 1/81 centrosome organization biological_process "A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a centrosome, a structure comprised of a pair of centrioles and peri-centriolar material from which a microtubule spindle apparatus is organized." [GOC:ai, GOC:dph, GOC:jl, GOC:mah] EOG8W6R90 GO:0046331 1/81 lateral inhibition biological_process "Signaling between cells of equivalent developmental potential that results in these cells adopting different developmental fates. An example is the suppression by cells with a particular fate of the adoption of the same fate by surrounding cells." [GOC:bf, GOC:kmv] EOG8W6R90 GO:0005814 1/81 centriole cellular_component "A cellular organelle, found close to the nucleus in many eukaryotic cells, consisting of a small cylinder with microtubular walls, 300-500 nm long and 150-250 nm in diameter. It contains nine short, parallel, peripheral microtubular fibrils, each fibril consisting of one complete microtubule fused to two incomplete microtubules. Cells usually have two centrioles, lying at right angles to each other. At division, each pair of centrioles generates another pair and the twin pairs form the pole of the mitotic spindle." [ISBN:0198547684] EOG8W6R90 GO:0032053 1/81 ciliary basal body organization biological_process "A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a ciliary basal body, a short cylindrical array of microtubules and associated proteins found at the base of a eukaryotic cilium (also called flagellum)." [GOC:cilia, GOC:dph, GOC:jl, GOC:mah, PMID:9889124] EOG8W6R90 GO:0036064 1/81 ciliary basal body cellular_component "A membrane-tethered, short cylindrical array of microtubules and associated proteins found at the base of a eukaryotic cilium (also called flagellum) that is similar in structure to a centriole and derives from it. The cilium basal body is the site of assembly and remodelling of the cilium and serves as a nucleation site for axoneme growth. As well as anchoring the cilium, it is thought to provide a selective gateway regulating the entry of ciliary proteins and vesicles by intraflagellar transport." [GOC:cilia, GOC:clt, PMID:21750193]
