FunFam 27: Putative syntaxin-3

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).
1 P91409 (/IPI)

There are 8 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
Synaptic vesicle docking GO:0016081
The initial (indirect) attachment of a synaptic vesicle membrane to the presynaptic active zone membrane, mediated by proteins protruding from the membrane and proteins of the presynaptic active zone cytoplasmic component. Synaptic vesicle tethering is the first step in this process.
2 P91409 (/ISS) Q20024 (/ISS)
Regulation of muscle contraction GO:0006937
Any process that modulates the frequency, rate or extent of muscle contraction.
1 Q20024 (/IGI)
Regulation of exocytosis GO:0017157
Any process that modulates the frequency, rate or extent of exocytosis.
1 P91409 (/IMP)
Positive regulation of cytokinesis GO:0032467
Any process that activates or increases the frequency, rate or extent of the division of the cytoplasm of a cell, and its separation into two daughter cells.
1 P91409 (/IMP)
Cortical granule exocytosis GO:0060471
The process of secretion by a cell that results in the release of intracellular molecules contained within a cortical granule by fusion of the vesicle with the plasma membrane of a cell. A cortical granule is a specialized secretory vesicle that is released during egg activation that changes the surface of the egg to prevent polyspermy.
1 P91409 (/IMP)
Membrane fusion GO:0061025
The membrane organization process that joins two lipid bilayers to form a single membrane.
1 Q20024 (/ISS)
Positive regulation of defecation GO:2000294
Any process that activates or increases the frequency, rate or extent of defecation.
1 Q20024 (/IGI)
Positive regulation of defecation GO:2000294
Any process that activates or increases the frequency, rate or extent of defecation.
1 Q20024 (/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
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.
1 Q20024 (/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.
1 Q20024 (/ISS)
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.
1 P91409 (/IDA)
Cleavage furrow GO:0032154
The cleavage furrow is a plasma membrane invagination at the cell division site. The cleavage furrow begins as a shallow groove and eventually deepens to divide the cytoplasm.
1 P91409 (/IDA)
Perinuclear region of cytoplasm GO:0048471
Cytoplasm situated near, or occurring around, the nucleus.
1 P91409 (/IDA)
Cortical granule GO:0060473
A secretory vesicle that is stored under the cell membrane of an egg. These vesicles fuse with the egg plasma membrane as part of egg activation and are part of the block to polyspermy.
