Abstract:

Many members of the tumor necrosis factor receptor (TNFR) superfamily initiate intracellular signaling by recruiting TNFR-associated factors (TRAFs) through their cytoplasmic tails. TRAFs apparently recognize highly diverse receptor sequences. Crystal structures of the TRAF domain of human TRAF2 in complex with peptides from the TNFR family members CD40, CD30, Ox40, 4-1BB, and the EBV oncoprotein LMP1 revealed a conserved binding mode. A major TRAF2-binding consensus sequence, (P/S/A/T)x(Q/E)E, and a minor consensus motif, PxQxxD, can be defined from the structural analysis, which encompass all known TRAF2-binding sequences. The structural information provides a template for the further dissection of receptor binding specificity of TRAF2 and for the understanding of the complexity of TRAF-mediated signal transduction.


Function and Biology Annotations from the GeneOntology database. Only terms that fit at least two of the interacting proteins are shown.

Molecular function:

signal transducer activity Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response. GeneOntology

ubiquitin protein ligase binding Interacting selectively and non-covalently with a ubiquitin protein ligase enzyme, any of the E3 proteins. GeneOntology

Biological process:

protein complex assembly The aggregation, arrangement and bonding together of a set of components to form a protein complex. GeneOntology

tumor necrosis factor-mediated signaling pathway A series of molecular signals initiated by the binding of a tumor necrosis factor to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription. GeneOntology

positive regulation of I-kappaB kinase/NF-kappaB signaling Any process that activates or increases the frequency, rate or extent of I-kappaB kinase/NF-kappaB signaling. GeneOntology

regulation of immunoglobulin secretion Any process that modulates the frequency, rate or extent of the regulated release of immunoglobulins from a cell. GeneOntology

positive regulation of NF-kappaB transcription factor activity Any process that activates or increases the frequency, rate or extent of activity of the transcription factor NF-kappaB. GeneOntology

regulation of immune response Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus. GeneOntology

positive regulation of cytokine production Any process that activates or increases the frequency, rate or extent of production of a cytokine. GeneOntology

positive regulation of lymphocyte mediated immunity Any process that activates or increases the frequency, rate, or extent of lymphocyte mediated immunity. GeneOntology

positive regulation of hydrolase activity Any process that activates or increases the frequency, rate or extent of hydrolase activity, the catalysis of the hydrolysis of various bonds. GeneOntology

intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell. GeneOntology

response to stress Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a disturbance in organismal or cellular homeostasis, usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation). GeneOntology

positive regulation of MAP kinase activity Any process that activates or increases the frequency, rate or extent of MAP kinase activity. GeneOntology

positive regulation of lymphocyte activation Any process that activates or increases the frequency, rate or extent of lymphocyte activation. GeneOntology

apoptotic signaling pathway A series of molecular signals which triggers the apoptotic death of a cell. The pathway starts with reception of a signal, and ends when the execution phase of apoptosis is triggered. GeneOntology

cellular response to oxygen-containing compound Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an oxygen-containing compound stimulus. GeneOntology

response to nitrogen compound Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nitrogen compound stimulus. GeneOntology

positive regulation of apoptotic process Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. GeneOntology

Cellular component:

cytoplasm All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. GeneOntology

CD40 receptor complex A protein complex that contains at least CD40 (a cell surface receptor of the tumour necrosis factor receptor (TNFR) superfamily), and other signaling molecules. GeneOntology

intracellular membrane-bounded organelle Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. GeneOntology

vesicle Any small, fluid-filled, spherical organelle enclosed by membrane. GeneOntology
