FunFam 127: Syntaxin-121

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 2 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 Q9ZSD4 (/IPI) Q9ZSD4 (/IPI)
Protein membrane anchor GO:0043495
Interacting selectively and non-covalently with both a protein or protein complex and a membrane, in order to maintain the localization of the protein at a specific membrane location.
2 Q9ZSD4 (/IDA) Q9ZSD4 (/IDA)

There are 10 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
Protein targeting to membrane GO:0006612
The process of directing proteins towards a membrane, usually using signals contained within the protein.
2 Q9ZSD4 (/IDA) Q9ZSD4 (/IDA)
Defense response GO:0006952
Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
2 Q9ZSD4 (/TAS) Q9ZSD4 (/TAS)
Response to fungus GO:0009620
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 stimulus from a fungus.
2 Q9ZSD4 (/IMP) Q9ZSD4 (/IMP)
Response to abscisic acid GO:0009737
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 an abscisic acid stimulus.
2 Q9ZSD4 (/IEP) Q9ZSD4 (/IEP)
Regulation of stomatal movement GO:0010119
Any process that modulates the frequency, rate or extent of stomatal movement.
2 Q9ZSD4 (/IMP) Q9ZSD4 (/IMP)
Transpiration GO:0010148
Release of water by the plant into the air as water vapor mainly through leaves.
2 Q9ZSD4 (/IMP) Q9ZSD4 (/IMP)
Vesicle-mediated transport GO:0016192
A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.
2 Q9ZSD4 (/IMP) Q9ZSD4 (/IMP)
Negative regulation of defense response GO:0031348
Any process that stops, prevents, or reduces the frequency, rate or extent of a defense response.
2 Q9ZSD4 (/IMP) Q9ZSD4 (/IMP)
Defense response to fungus GO:0050832
Reactions triggered in response to the presence of a fungus that act to protect the cell or organism.
2 Q9ZSD4 (/IGI) Q9ZSD4 (/IGI)
Maintenance of protein location in plasma membrane GO:0072660
Any process in which a protein is maintained in a specific location in the plasma membrane, and is prevented from moving elsewhere.
2 Q9ZSD4 (/IMP) Q9ZSD4 (/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
Trans-Golgi network GO:0005802
The network of interconnected tubular and cisternal structures located within the Golgi apparatus on the side distal to the endoplasmic reticulum, from which secretory vesicles emerge. The trans-Golgi network is important in the later stages of protein secretion where it is thought to play a key role in the sorting and targeting of secreted proteins to the correct destination.
2 Q9ZSD4 (/IDA) Q9ZSD4 (/IDA)
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
2 Q9ZSD4 (/IDA) Q9ZSD4 (/IDA)
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
2 Q9ZSD4 (/TAS) Q9ZSD4 (/TAS)
Cell plate GO:0009504
The nascent cell membrane and cell wall structure that forms between two daughter nuclei near the center of a dividing plant cell. It develops at the equitorial region of the phragmoplast. It grows outwards to join with the lateral walls and form two daughter cells.
2 Q9ZSD4 (/IDA) Q9ZSD4 (/IDA)
Plasmodesma GO:0009506
A fine cytoplasmic channel, found in all higher plants, that connects the cytoplasm of one cell to that of an adjacent cell.
2 Q9ZSD4 (/IDA) Q9ZSD4 (/IDA)
SNARE complex GO:0031201
A protein complex involved in membrane fusion; a stable ternary complex consisting of a four-helix bundle, usually formed from one R-SNARE and three Q-SNAREs with an ionic layer sandwiched between hydrophobic layers. One well-characterized example is the neuronal SNARE complex formed of synaptobrevin 2, syntaxin 1a, and SNAP-25.
