Descriptions

CLASPs, major microtubule-stabilizing factors in interphase and mitosis, prevent microtubule from switching form growth to shortening by stabilizing growing microtubule ends, and thus suppress microtubule catastrophes. CLASP2a consists of three TOG-like domains (termed TOG1, 2, and 3) and a C-terminal domain, CLIP-interacting domain (CLIP-ID) responsible for interaction with CLIP-170 and other partners. CLASP2a TOG2 is necessary and sufficient for catastrophe inhibition. The inhibition function is suppressed by the C-terminal domain CLIP-ID while the TOG1 domain or the CLIP-ID partner binding to CLIP-ID can release the autoinhibition.

12 GO annotations of cellular component

Name Definition
basal cortex The region that lies just beneath the plasma membrane on the basal edge of a cell.
cell leading edge The area of a motile cell closest to the direction of movement.
centrosome 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.
cytoplasmic microtubule Any microtubule in the cytoplasm of a cell.
Golgi apparatus A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways.
kinetochore A multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules.
microtubule Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle.
microtubule organizing center An intracellular structure that can catalyze gamma-tubulin-dependent microtubule nucleation and that can anchor microtubules by interacting with their minus ends, plus ends or sides.
mitotic spindle A spindle that forms as part of mitosis. Mitotic and meiotic spindles contain distinctive complements of proteins associated with microtubules.
ruffle membrane The portion of the plasma membrane surrounding a ruffle.
spindle microtubule Any microtubule that is part of a mitotic or meiotic spindle; anchored at one spindle pole.
trans-Golgi network The network of interconnected tubular and cisternal structures located within the Golgi apparatus on the side distal to the endoplasmic reticulum, from which secretory vesicles emerge. The trans-Golgi network is important in the later stages of protein secretion where it is thought to play a key role in the sorting and targeting of secreted proteins to the correct destination.

Name Definition
microtubule binding Binding to a microtubule, a filament composed of tubulin monomers.
microtubule plus-end binding Binding to the plus end of a microtubule.

13 GO annotations of biological process

Name Definition
cell division The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.
establishment of mitotic spindle localization The cell cycle process in which the directed movement of the mitotic spindle to a specific location in the cell occurs.
exit from mitosis The cell cycle transition where a cell leaves M phase and enters a new G1 phase. M phase is the part of the mitotic cell cycle during which mitosis and cytokinesis take place.
Golgi organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the Golgi apparatus.
hematopoietic stem cell homeostasis Any biological process involved in the maintenance of the steady-state number of hematopoietic stem cells within a population of cells.
microtubule anchoring Any process in which a microtubule is maintained in a specific location in a cell.
microtubule 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 microtubules and their associated proteins.
microtubule nucleation The process in which tubulin alpha-beta heterodimers begin aggregation to form an oligomeric tubulin structure (a microtubule seed). Microtubule nucleation is the initiating step in the formation of a microtubule in the absence of any existing microtubules ('de novo' microtubule formation).
microtubule organizing center organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a microtubule organizing center, a structure from which microtubules grow.
mitotic spindle assembly Mitotic bipolar spindle assembly begins with spindle microtubule nucleation from the separated spindle pole body, includes spindle elongation during prometaphase, and is complete when all kinetochores are stably attached the spindle, and the spindle assembly checkpoint is satisfied.
mitotic spindle organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the microtubule spindle during a mitotic cell cycle.
regulation of microtubule polymerization or depolymerization Any process that modulates the frequency, rate or extent of microtubule polymerization or depolymerization by the addition or removal of tubulin heterodimers from a microtubule.
regulation of microtubule-based process Any process that modulates the frequency, rate or extent of any cellular process that depends upon or alters the microtubule cytoskeleton.
