Descriptions

Ephrin type-B receptor 2 is a membrane-associated protein that mediates axon guidance, cell migration and morphogenesis. The Eph receptor tyrosine kinase family is regulated by autophosphorylation within the juxtamembrane region and the kinase activation segment. The structure, supported by mutagenesis data, reveals that the juxtamembrane segment adopts a helical conformation that distorts the small lobe of the kinase domain, and blocks the activation segment from attaining an activated conformation. Phosphorylation of the conserved juxtamembrane tyrosines would relieve this autoinhibition by disturbing the association of the juxtamembrane segment with the kinase domain, while liberating phosphotyrosine sites for binding SH2 domains of target proteins.

4 GO annotations of cellular component

Name Definition
dendrite A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
early endosome membrane The lipid bilayer surrounding an early endosome.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
receptor complex Any protein complex that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

3 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
transmembrane receptor protein tyrosine kinase activity Combining with a signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity by catalysis of the reaction
transmembrane-ephrin receptor activity Combining with a transmembrane ephrin to initiate a change in cell activity.

11 GO annotations of biological process

Name Definition
axon guidance The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.
cell chemotaxis The directed movement of a motile cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).
cell-substrate adhesion The attachment of a cell to the underlying substrate via adhesion molecules.
dendritic spine development The process whose specific outcome is the progression of the dendritic spine over time, from its formation to the mature structure. A dendritic spine is a protrusion from a dendrite and a specialized subcellular compartment involved in synaptic transmission.
dendritic spine morphogenesis The process in which the anatomical structures of a dendritic spine are generated and organized. A dendritic spine is a protrusion from a dendrite and a specialized subcellular compartment involved in synaptic transmission.
ephrin receptor signaling pathway The series of molecular signals initiated by ephrin binding to its receptor, and ending with the regulation of a downstream cellular process, e.g. transcription.
establishment of cell polarity The specification and formation of anisotropic intracellular organization or cell growth patterns.
positive regulation of synapse assembly Any process that activates, maintains or increases the frequency, rate or extent of synapse assembly, the aggregation, arrangement and bonding together of a set of components to form a synapse.
protein autophosphorylation The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).
regulation of ERK1 and ERK2 cascade Any process that modulates the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.
regulation of JNK cascade Any process that modulates the frequency, rate or extent of signal transduction mediated by the JNK cascade.
