FunFam 3560:

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).
2 Q9FIE3 (/IPI) Q9FIE3 (/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
Response to hypoxia GO:0001666
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 indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level.
2 Q9FIE3 (/IMP) Q9FIE3 (/IMP)
Response to cold GO:0009409
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 cold stimulus, a temperature stimulus below the optimal temperature for that organism.
2 Q9FIE3 (/IEP) Q9FIE3 (/IEP)
Vernalization response GO:0010048
The process of thermal induction in plants in which flowering is promoted by exposure to low temperatures.
2 Q9FIE3 (/IEP) Q9FIE3 (/IEP)
Vernalization response GO:0010048
The process of thermal induction in plants in which flowering is promoted by exposure to low temperatures.
2 Q9FIE3 (/IMP) Q9FIE3 (/IMP)
Negative regulation of gene expression, epigenetic GO:0045814
Any epigenetic process that stops, prevents or reduces the rate of gene expression.
2 Q9FIE3 (/IMP) Q9FIE3 (/IMP)
Positive regulation of histone H3-K4 methylation GO:0051571
Any process that activates or increases the frequency, rate or extent of the covalent addition of a methyl group to the lysine at position 4 of histone H3.
2 Q9FIE3 (/IMP) Q9FIE3 (/IMP)
Positive regulation of histone H3-K27 methylation GO:0061087
Any process that increases the rate, frequency, or extent of histone H3-K27 methylation. Histone H3-K27 methylation is the modification of histone H3 by addition of a methyl group to lysine at position 27 of the histone.
2 Q9FIE3 (/IMP) Q9FIE3 (/IMP)
Cellular response to cold GO:0070417
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cold stimulus, a temperature stimulus below the optimal temperature for that organism.

There are 3 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
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
2 Q9FIE3 (/IDA) Q9FIE3 (/IDA)
Chromatin silencing complex GO:0005677
Any protein complex that mediates changes in chromatin structure that result in transcriptional silencing.
2 Q9FIE3 (/IDA) Q9FIE3 (/IDA)
Nuclear speck GO:0016607
A discrete extra-nucleolar subnuclear domain, 20-50 in number, in which splicing factors are seen to be localized by immunofluorescence microscopy.
