Descriptions

KIF17 is dendrite-specific motor protein which, in association with the Apba1-containing complex (LIN-10-LIN-2-LIN-7 complex), transports vesicles containing N-methyl-D-aspartate (NMDA) receptor subunit NR2B along microtubules. <br> Two molecular mechanisms contribute to autoinhibition of KIF17. First, the C-terminal tail interferes with microtubule binding. Second, a CC2 segment blocks processive motility.The CC2 and tail segments inhibit KIF17 motility via direct interactions with the motor domain.

Name Definition
axoneme The bundle of microtubules and associated proteins that forms the core of cilia (also called flagella) in eukaryotic cells and is responsible for their movements.
ciliary basal body 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.
cilium A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface and of some cytoplasmic parts. Each cilium is largely bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored to a basal body.
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
dendrite cytoplasm All of the contents of a dendrite, excluding the surrounding plasma membrane.
kinesin complex Any complex that includes a dimer of molecules from the kinesin superfamily, a group of related proteins that contain an extended region of predicted alpha-helical coiled coil in the main chain that likely produces dimerization. The native complexes of several kinesin family members have also been shown to contain additional peptides, often designated light chains as all of the noncatalytic subunits that are currently known are smaller than the chain that contains the motor unit. Kinesin complexes generally possess a force-generating enzymatic activity, or motor, which converts the free energy of the gamma phosphate bond of ATP into mechanical work.
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 cytoskeleton The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins.
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.
neuron projection A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.
periciliary membrane compartment A plasma membrane region adjacent to the base of eukaryotic cilia and flagella that is enriched in endocytosis-associated proteins and vesicles and that appears to regulate ciliary membrane homeostasis.
photoreceptor connecting cilium The portion of the photoreceptor cell cilium linking the photoreceptor inner and outer segments. It's considered to be equivalent to the ciliary transition zone.
photoreceptor inner segment The inner segment of a vertebrate photoreceptor containing mitochondria, ribosomes and membranes where opsin molecules are assembled and passed to be part of the outer segment discs.
photoreceptor outer segment The outer segment of a vertebrate photoreceptor that contains a stack of membrane discs embedded with photoreceptor proteins.

9 GO annotations of biological process

Name Definition
anterograde dendritic transport of neurotransmitter receptor complex The directed movement of a neurotransmitter receptor complex along microtubules in nerve cell dendrites towards the postsynapse.
cell projection organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a prolongation or process extending from a cell, e.g. a flagellum or axon.
intraciliary transport The bidirectional movement of large protein complexes along microtubules within a cilium, mediated by motor proteins.
microtubule-based process Any cellular process that depends upon or alters the microtubule cytoskeleton, that part of the cytoskeleton comprising microtubules and their associated proteins.
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.
protein transport The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
protein-containing complex localization A localization process that acts on a protein complex; the complex is transported to, or maintained in, a specific location.
spindle elongation The cell cycle process in which the distance is lengthened between poles of the spindle.
vesicle-mediated transport A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.
