FunFam 228: Ribosome-inactivating protein momordin I

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 8 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
RRNA N-glycosylase activity GO:0030598
Catalysis of the hydrolysis of the N-glycosylic bond at A-4324 in 28S rRNA from rat ribosomes or corresponding sites in 28S RNA from other species.
6 P84853 (/IDA) P84854 (/IDA) P85101 (/IDA) Q6EH50 (/IDA) Q9M653 (/IDA) Q9M654 (/IDA)
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 P02879 (/IPI) P06750 (/IPI)
Galactose binding GO:0005534
Interacting selectively and non-covalently with the aldohexose galactose (galacto-hexose), a common constituent of many oligo- and polysaccharides.
1 P11140 (/TAS)
Hydrolase activity GO:0016787
Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
1 Q6EH50 (/IDA)
Carbohydrate binding GO:0030246
Interacting selectively and non-covalently with any carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates.
1 Q9M6E9 (/TAS)
RNA glycosylase activity GO:0030597
Catalysis of the hydrolysis of N-glycosidic bonds in an RNA molecule.
1 P85101 (/IDA)
RRNA N-glycosylase activity GO:0030598
Catalysis of the hydrolysis of the N-glycosylic bond at A-4324 in 28S rRNA from rat ribosomes or corresponding sites in 28S RNA from other species.
1 Q9M6E9 (/NAS)
RRNA N-glycosylase activity GO:0030598
Catalysis of the hydrolysis of the N-glycosylic bond at A-4324 in 28S rRNA from rat ribosomes or corresponding sites in 28S RNA from other species.

There are 7 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
Negative regulation of translation GO:0017148
Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA.
4 P84853 (/IDA) P84854 (/IDA) Q6EH50 (/IDA) Q9M6E9 (/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 P84853 (/IDA) P84854 (/IDA)
Heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules GO:0007157
The attachment of an adhesion molecule in one cell to a nonidentical adhesion molecule in an adjacent cell.
1 Q9M6E9 (/NAS)
Negative regulation of translation GO:0017148
Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA.
1 P11140 (/TAS)
Killing of cells of other organism GO:0031640
Any process in an organism that results in the killing of cells of another organism, including in some cases the death of the other organism. Killing here refers to the induction of death in one cell by another cell, not cell-autonomous death due to internal or other environmental conditions.
1 P02879 (/IDA)
Positive regulation of apoptotic process in other organism GO:0044533
Any process in which an organism activates, maintains or increases the frequency, rate or extent of programmed cell death by apoptosis in a second organism.
1 Q9M6E9 (/IDA)
Positive regulation of endocytosis GO:0045807
Any process that activates or increases the frequency, rate or extent of endocytosis.

There are 2 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).
2 P02879 (/IDA) P06750 (/IDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
