| | GO:0005089 | | Rho guanyl-nucleotide exchange factor activity | | Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family.

| | GO:0005085 | | guanyl-nucleotide exchange factor activity | | Stimulates the exchange of guanyl nucleotides associated with a GTPase. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase. |
| | GO:0019209 | | kinase activator activity | | Binds to and increases the activity of a kinase, an enzyme which catalyzes of the transfer of a phosphate group, usually from ATP, to a substrate molecule. |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0070064 | | proline-rich region binding | | Interacting selectively and non-covalently with a proline-rich region, i.e. a region that contains a high proportion of proline residues, in a protein. |
| | GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| | GO:0032947 | | protein complex scaffold activity | | A structural molecule activity that provides a physical support for the assembly of a multiprotein complex. The scaffold may or may not be part of the final complex. |
| biological process |
|---|
| | GO:0006897 | | endocytosis | | A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle. |
| | GO:0048013 | | ephrin receptor signaling pathway | | The series of molecular signals generated as a consequence of an ephrin receptor binding to an ephrin. |
| | GO:0035556 | | 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. |
| | GO:0043524 | | negative regulation of neuron apoptotic process | | Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process in neurons. |
| | GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| | GO:0042327 | | positive regulation of phosphorylation | | Any process that activates or increases the frequency, rate or extent of addition of phosphate groups to a molecule. |
| | GO:0051897 | | positive regulation of protein kinase B signaling | | Any process that activates or increases the frequency, rate or extent of protein kinase B signaling, a series of reactions mediated by the intracellular serine/threonine kinase protein kinase B. |
| | GO:0035023 | | regulation of Rho protein signal transduction | | Any process that modulates the frequency, rate or extent of Rho protein signal transduction. |
| | GO:0007264 | | small GTPase mediated signal transduction | | Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals. |
| cellular component |
|---|
| | GO:0030054 | | cell junction | | A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix. |
| | GO:0042995 | | cell projection | | A prolongation or process extending from a cell, e.g. a flagellum or axon. |
| | GO:0005905 | | clathrin-coated pit | | A part of the endomembrane system in the form of an invagination of a membrane upon which a clathrin coat forms, and that can be converted by vesicle budding into a clathrin-coated vesicle. Coated pits form on the plasma membrane, where they are involved in receptor-mediated selective transport of many proteins and other macromolecules across the cell membrane, in the trans-Golgi network, and on some endosomes. |
| | GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:0030139 | | endocytic vesicle | | A membrane-bounded intracellular vesicle formed by invagination of the plasma membrane around an extracellular substance. Endocytic vesicles fuse with early endosomes to deliver the cargo for further sorting. |
| | GO:0012505 | | endomembrane system | | A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles. |
| | GO:0030027 | | lamellipodium | | A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0043005 | | neuron projection | | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| | GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| | GO:0045202 | | synapse | | The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. |
