FunFam 138604: Immunoglobulin 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 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
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).
3 A4IG39 (/IPI) Q9U3P2 (/IPI) Q9U3P2 (/IPI)
Protein homodimerization activity GO:0042803
Interacting selectively and non-covalently with an identical protein to form a homodimer.
2 Q9U3P2 (/IPI) Q9U3P2 (/IPI)
Cell adhesion molecule binding GO:0050839
Interacting selectively and non-covalently with a cell adhesion molecule.
2 Q9U3P2 (/IPI) Q9U3P2 (/IPI)

There are 6 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
Cell-cell signaling GO:0007267
Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.
2 Q9U3P2 (/IMP) Q9U3P2 (/IMP)
Synapse assembly GO:0007416
The aggregation, arrangement and bonding together of a set of components to form a synapse. This process ends when the synapse is mature (functional).
2 Q9U3P2 (/IMP) Q9U3P2 (/IMP)
Synaptic target recognition GO:0008039
The process in which a neuronal cell in a multicellular organism interprets signals produced by potential target cells, with which it may form synapses.
2 Q9U3P2 (/IMP) Q9U3P2 (/IMP)
Protein localization to synapse GO:0035418
Any process in which a protein is transported to, and/or maintained at the synapse, the junction between a nerve fiber of one neuron and another neuron or muscle fiber or glial cell.
2 Q9U3P2 (/IMP) Q9U3P2 (/IMP)
Collateral sprouting GO:0048668
The process in which outgrowths develop from the shafts of existing axons.
2 Q9U3P2 (/IMP) Q9U3P2 (/IMP)
Synapse organization GO:0050808
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a synapse, the junction between a neuron and a target (neuron, muscle, or secretory cell).

There are 1 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
Integral component of plasma membrane GO:0005887
The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
