The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Neurotransmitter-gated ion-channel ligand-binding domain

FunFam 35: Ligand-Gated ion Channel

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 3 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 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.
3 H2L0B8 (/IDA) Q8MPU3 (/IDA) Q9GQ00 (/IDA)
Extracellular ligand-gated ion channel activity GO:0005230
Enables the transmembrane transfer of an ion by a channel that opens when a specific extracellular ligand has been bound by the channel complex or one of its constituent parts.
3 H2L0B8 (/IDA) Q8MPU3 (/IDA) Q9GQ00 (/IDA)
Chloride channel activity GO:0005254
Enables the facilitated diffusion of a chloride (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
