FunFam 49: SEcretin/class B GPCR

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 1 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
G protein-coupled receptor activity GO:0004930
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.
1 G5EBF7 (/ISS)

There are 5 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
G protein-coupled receptor signaling pathway GO:0007186
A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).
1 G5EBF7 (/ISS)
Locomotory behavior GO:0007626
The specific movement from place to place of an organism in response to external or internal stimuli. Locomotion of a whole organism in a manner dependent upon some combination of that organism's internal state and external conditions.
1 G5EBF7 (/IGI)
Locomotory behavior GO:0007626
The specific movement from place to place of an organism in response to external or internal stimuli. Locomotion of a whole organism in a manner dependent upon some combination of that organism's internal state and external conditions.
1 G5EBF7 (/IMP)
Response to heat GO:0009408
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 heat stimulus, a temperature stimulus above the optimal temperature for that organism.
1 G5EBF7 (/IMP)
Behavioral response to ethanol GO:0048149
Any process that results in a change in the behavior of an organism as a result of an ethanol stimulus.
1 G5EBF7 (/IMP)

There are 4 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Axon GO:0030424
The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.
1 G5EBF7 (/IDA)
Axolemma GO:0030673
The portion of the plasma membrane surrounding an axon; it is a specialized trilaminar random mosaic of protein molecules floating within a fluid matrix of highly mobile phospholipid molecules, 7-8 nm in thickness.
1 G5EBF7 (/IC)
Neuronal cell body membrane GO:0032809
The plasma membrane of a neuron cell body - excludes the plasma membrane of cell projections such as axons and dendrites.
1 G5EBF7 (/IC)
Neuronal cell body GO:0043025
The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.
