The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Phosphatidylinositol 3-kinase Catalytic Subunit; Chain A, domain 1
".

FunFam 208: Small ubiquitin-related modifier

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).
1 O13351 (/IPI)
Protein tag GO:0031386
A molecular function exhibited by a protein that is covalently attached (AKA tagged or conjugated) to another protein where it acts as a marker, recognized by the cellular apparatus to target the tagged protein for some cellular process such as modification, sequestration, transport or degradation.
1 O13351 (/IDA)

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
Telomere maintenance GO:0000723
Any process that contributes to the maintenance of proper telomeric length and structure by affecting and monitoring the activity of telomeric proteins, the length of telomeric DNA and the replication and repair of the DNA. These processes includes those that shorten, lengthen, replicate and repair the telomeric DNA sequences.
1 O13351 (/IMP)
Protein sumoylation GO:0016925
The process in which a SUMO protein (small ubiquitin-related modifier) is conjugated to a target protein via an isopeptide bond between the carboxy-terminus of SUMO with an epsilon-amino group of a lysine residue of the target protein.
1 O13351 (/IDA)
Chromatin silencing at silent mating-type cassette GO:0030466
Repression of transcription at silent mating-type loci by alteration of the structure of chromatin.
1 O13351 (/IMP)
Chromatin silencing at centromere GO:0030702
Repression of transcription of centromeric DNA by altering the structure of chromatin.
1 O13351 (/IMP)
Negative regulation of histone H3-K4 methylation GO:0051572
Any process that stops, prevents, or reduces the frequency, rate or extent of the covalent addition of a methyl group to the lysine at position 4 of histone H3.
1 O13351 (/IMP)
Negative regulation of histone H3-K9 methylation GO:0051573
Any process that stops, prevents, or reduces the frequency, rate or extent of the covalent addition of a methyl group to the lysine at position 9 of histone H3.
1 O13351 (/IMP)
Negative regulation of histone H3-K14 acetylation GO:0071441
Any process that stops, prevents, or reduces the frequency, rate or extent of the addition of an acetyl group to histone H3 at position 14 of the histone.
1 O13351 (/IMP)

There are 5 GO terms relating to "cellular component"

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.
1 O13351 (/HDA)

In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
1 O13351 (/IDA)
Linear element GO:0030998
A proteinaceous scaffold associated with fission yeast chromosomes during meiotic prophase. Linear elements consist of a protein complex, LinE, with four main structural components (Rec10, Rec25, Rec27, and Mug20 in S. pombe) associated with chromatin. The resulting structure is related to but not equivalent to the synaptonemal complex.
1 O13351 (/IDA)
Mitotic spindle pole body GO:0044732
The microtubule organizing center that forms as part of the mitotic cell cycle; functionally homologous to the animal cell centrosome.
1 O13351 (/HDA)
Mitotic spindle pole body GO:0044732
The microtubule organizing center that forms as part of the mitotic cell cycle; functionally homologous to the animal cell centrosome.
