GO:0004871
|
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. |
GO:0004872
|
receptor activity
|
Combining with an extracellular or intracellular messenger to initiate a change in cell activity. |
GO:0004930
|
G-protein coupled receptor activity
|
Combining with an extracellular signal and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. |
GO:0004888
|
transmembrane signaling receptor activity
|
Combining with an extracellular or intracellular signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity. |
GO:0003674
|
molecular_function
|
Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
GO:0038023
|
signaling receptor activity
|
Receiving a signal and transmitting the signal in the cell to initiate a change in cell activity. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response. |
GO:0060089
|
molecular transducer activity
|
The molecular function that accepts an input of one form and creates an output of a different form. |
GO:0001608
|
G-protein coupled nucleotide receptor activity
|
Combining with a nucleotide and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. |
GO:0035586
|
purinergic receptor activity
|
Combining with a purine or purine derivative (purine nucleoside or purine nucleotide) and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity. A nucleotide is a compound that consists of a nucleoside esterified with a phosphate molecule. |
GO:0001614
|
purinergic nucleotide receptor activity
|
Combining with a purine nucleotide and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity. |
GO:0016502
|
nucleotide receptor activity
|
Combining with a nucleotide and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity. A nucleotide is a compound that consists of a nucleoside esterified with a phosphate molecule. |
GO:0045028
|
G-protein coupled purinergic nucleotide receptor activity
|
Combining with a purine nucleotide and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. |
