Functions
6 GO annotations of cellular component
| Name | Definition |
|---|---|
| adherens junction | A cell-cell junction composed of the epithelial cadherin-catenin complex. The epithelial cadherins, or E-cadherins, of each interacting cell extend through the plasma membrane into the extracellular space and bind to each other. The E-cadherins bind to catenins on the cytoplasmic side of the membrane, where the E-cadherin-catenin complex binds to cytoskeletal components and regulatory and signaling molecules. |
| axon | The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter. |
| catenin complex | Complex of peripheral cytoplasmic proteins (alpha-, beta- and gamma-catenin) that interact with the cytoplasmic region of uvomorulin/E-cadherin to connect it to the actin cytoskeleton. |
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| cytoskeleton | A cellular structure that forms the internal framework of eukaryotic and prokaryotic cells. The cytoskeleton includes intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles. |
| nucleus | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
3 GO annotations of molecular function
| Name | Definition |
|---|---|
| actin filament binding | Binding to an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits. |
| beta-catenin binding | Binding to a catenin beta subunit. |
| cadherin binding | Binding to cadherin, a type I membrane protein involved in cell adhesion. |
6 GO annotations of biological process
| Name | Definition |
|---|---|
| axonogenesis | De novo generation of a long process of a neuron, including the terminal branched region. Refers to the morphogenesis or creation of shape or form of the developing axon, which carries efferent (outgoing) action potentials from the cell body towards target cells. |
| brain morphogenesis | The process in which the anatomical structures of the brain are generated and organized. The brain is one of the two components of the central nervous system and is the center of thought and emotion. It is responsible for the coordination and control of bodily activities and the interpretation of information from the senses (sight, hearing, smell, etc.). |
| cell migration | The controlled self-propelled movement of a cell from one site to a destination guided by molecular cues. |
| cell-cell adhesion | The attachment of one cell to another cell via adhesion molecules. |
| dendrite morphogenesis | The process in which the anatomical structures of a dendrite are generated and organized. |
| regulation of synapse structural plasticity | Any process that modulates the frequency, rate or extent of synapse structural plasticity. Synapse structural plasticity is a type of cytoskeletal remodeling; this remodeling is induced by stimuli that can lead to long term potentiation and it can be activity-dependent or -independent. Examples of cytoskeletal changes include the formation of new spines and increase in spine size; this can be accompanied by the insertion of greater numbers of glutamate (or other neurotransmitter) receptors into the post-synaptic membrane. |
