Descriptions

Death receptor-5 (DR5) belongs to the tumor necrosis factor alpha (TNF-alpha) superfamily, contains three external cysteine-rich domain (CRD1-CRD3), and activates apoptotic signaling outside of cells. The negative regulatory function of a critical patch of positively charged residues (PPCR) within the CRD3 domain of DR3 is disrupted by sustained antibody binding, resulting in highly effective clustering of DR5 and apoptotic clustering to tumors.

4 GO annotations of cellular component

Name Definition
membrane raft Any of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions.
neuron projection membrane The portion of the plasma membrane surrounding a neuron projection.
neuronal cell body membrane The plasma membrane of a neuron cell body - excludes the plasma membrane of cell projections such as axons and dendrites.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

1 GO annotations of molecular function

Name Definition
netrin receptor activity Combining with a netrin signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.

5 GO annotations of biological process

Name Definition
anterior/posterior axon guidance The process in which the migration of an axon growth cone is directed to a specific target site along the anterior-posterior body axis in response to a combination of attractive and repulsive cues. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism.
apoptotic process A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.
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.
netrin-activated signaling pathway The series of molecular signals initiated by the binding of a netrin protein to its receptor on the surface of the target cell, and ending with the regulation of a downstream cellular process, e.g. transcription. Netrins can act as chemoattractant signals for some cells and chemorepellent signals for others. Netrins also have roles outside of cell and axon guidance.
neuron projection development The process whose specific outcome is the progression of a neuron projection over time, from its formation to the mature structure. A neuron projection is any process extending from a neural cell, such as axons or dendrites (collectively called neurites).
