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:

"

FunFam 509: Immunoglobin superfamily member 21

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
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
2 A4IG39 (/IPI) Q7TNR6 (/IPI)

There are 2 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
Synapse maturation GO:0060074
The process that organizes a synapse so that it attains its fully functional state. Synaptic maturation plays a critical role in the establishment of effective synaptic connections in early development.
2 M0RAS4 (/ISS) Q96ID5 (/ISS)
Synapse maturation GO:0060074
The process that organizes a synapse so that it attains its fully functional state. Synaptic maturation plays a critical role in the establishment of effective synaptic connections in early development.
1 Q7TNR6 (/IMP)

There are 6 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
Anchored component of external side of plasma membrane GO:0031362
The component of the plasma membrane consisting of the gene products that are tethered to the external side of the membrane only by a covalently attached anchor, such as a lipid group embedded in the membrane. Gene products with peptide sequences that are embedded in the membrane are excluded from this grouping.
2 M0RAS4 (/ISS) Q96ID5 (/ISS)
Presynaptic membrane GO:0042734
A specialized area of membrane of the axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane.
2 M0RAS4 (/ISS) Q96ID5 (/ISS)
Inhibitory synapse GO:0060077
A synapse in which an action potential in the presynaptic cell reduces the probability of an action potential occurring in the postsynaptic cell.
2 M0RAS4 (/ISS) Q96ID5 (/ISS)
Anchored component of external side of plasma membrane GO:0031362
The component of the plasma membrane consisting of the gene products that are tethered to the external side of the membrane only by a covalently attached anchor, such as a lipid group embedded in the membrane. Gene products with peptide sequences that are embedded in the membrane are excluded from this grouping.
1 Q7TNR6 (/IDA)
Presynaptic membrane GO:0042734
A specialized area of membrane of the axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane.
1 Q7TNR6 (/IDA)
Inhibitory synapse GO:0060077
A synapse in which an action potential in the presynaptic cell reduces the probability of an action potential occurring in the postsynaptic cell.
