FunFam 310: 5-hydroxytryptamine receptor 2B

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 5 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
Gi/o-coupled serotonin receptor activity GO:0001586
Combining with serotonin and transmitting the signal across the membrane by activation of the Gi/o subunit of an associated cytoplasmic heterotrimeric G protein complex. The Gi/o subunit subsequently inhibits adenylate cyclase and results in a decrease in cyclic AMP (cAMP) levels.
2 P28285 (/NAS) P28286 (/NAS)
G protein-coupled serotonin receptor activity GO:0004993
Combining with the biogenic amine serotonin and transmitting the signal across the membrane by activating an associated G-protein. Serotonin (5-hydroxytryptamine) is a neurotransmitter and hormone found in vertebrates and invertebrates.
2 P28285 (/IDA) P28286 (/IDA)
G protein-coupled serotonin receptor activity GO:0004993
Combining with the biogenic amine serotonin and transmitting the signal across the membrane by activating an associated G-protein. Serotonin (5-hydroxytryptamine) is a neurotransmitter and hormone found in vertebrates and invertebrates.
2 P28285 (/ISS) P28286 (/ISS)
G protein-coupled serotonin receptor activity GO:0004993
Combining with the biogenic amine serotonin and transmitting the signal across the membrane by activating an associated G-protein. Serotonin (5-hydroxytryptamine) is a neurotransmitter and hormone found in vertebrates and invertebrates.
2 P28285 (/TAS) P28286 (/TAS)
G protein-coupled amine receptor activity GO:0008227
Combining with an extracellular amine 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.
