FunFam 14: Tetraspanin

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 B2R9H7 (/IPI) P38573 (/IPI)
Structural molecule activity GO:0005198
The action of a molecule that contributes to the structural integrity of a complex or its assembly within or outside a cell.
1 O75841 (/NAS)

There are 4 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
Response to bacterium GO:0009617
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 bacterium.
1 Q9Z2C6 (/IEP)
Epithelial cell differentiation GO:0030855
The process in which a relatively unspecialized cell acquires specialized features of an epithelial cell, any of the cells making up an epithelium.
1 O75841 (/IDA)
Epithelial cell differentiation GO:0030855
The process in which a relatively unspecialized cell acquires specialized features of an epithelial cell, any of the cells making up an epithelium.
1 Q9Z2C6 (/ISO)
Protein localization to cell surface GO:0034394
A process in which a protein is transported to, or maintained in, a location within the external part of the cell wall and/or plasma membrane.
1 P38573 (/IPI)

There are 7 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
Endoplasmic reticulum GO:0005783
The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
1 P38573 (/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 P38573 (/IDA)
Integral component of membrane GO:0016021
The component of a 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 P38573 (/IDA)
Integral component of membrane GO:0016021
The component of a 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 O75841 (/NAS)
Apical plasma membrane GO:0016324
The region of the plasma membrane located at the apical end of the cell.
1 Q9Z2C6 (/IDA)
Extracellular exosome GO:0070062
A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
1 O75841 (/HDA)
Apical plasma membrane urothelial plaque GO:0120001
A scallop-shaped plaque, also referred to as an asymmetric unit membrane (AUM), found in the apical plasma membrane of urothelial superficial (umbrella) cells which form a a barrier to the passage of water and soluble toxic compounds found in urine. The plaques are thickened regions of membrane composed of uroplakin transmembrane proteins which form a crystalline array.
