FunFam 920: E3 SUMO-protein ligase SIZ1

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
SUMO transferase activity GO:0019789
Catalysis of the transfer of SUMO from one protein to another via the reaction X-SUMO + Y --> Y-SUMO + X, where both X-SUMO and Y-SUMO are covalent linkages.

GO Term Annotations Evidence
Chromosome segregation GO:0007059
The process in which genetic material, in the form of chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets. In eukaryotes, chromosome segregation begins with the condensation of chromosomes, includes chromosome separation, and ends when chromosomes have completed movement to the spindle poles.
1 Q04195 (/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 carboxyl terminus of SUMO with an epsilon-amino group of a lysine residue of the target protein.
1 Q04195 (/IDA)
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 carboxyl terminus of SUMO with an epsilon-amino group of a lysine residue of the target protein.

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 carboxyl terminus of SUMO with an epsilon-amino group of a lysine residue of the target protein.
1 Q04195 (/IMP)
Negative regulation of protein ubiquitination GO:0031397
Any process that stops, prevents, or reduces the frequency, rate or extent of the addition of ubiquitin groups to a protein.
1 Q04195 (/IDA)
Negative regulation of protein ubiquitination GO:0031397
Any process that stops, prevents, or reduces the frequency, rate or extent of the addition of ubiquitin groups to a protein.
1 Q04195 (/IMP)
DNA double-strand break attachment to nuclear envelope GO:1990683
A process in which the DNA double-strand breaks are attached to the inner surface of the nuclear envelope proximal to the spindle pole body, or iMTOCs.

GO Term Annotations Evidence
Nuclear chromatin GO:0000790
The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome in the nucleus.
1 Q04195 (/IDA)
Septin ring GO:0005940
A tight ring-shaped structure that forms in the division plane at the site of cytokinesis; composed of members of the conserved family of filament-forming proteins called septins as well as septin-associated proteins. This type of septin structure is observed at the bud neck of budding fungal cells, at the site of cell division in animal cells, at the junction between the mother cell and a pseudohyphal projection, and also within hyphae of filamentous fungi at sites where a septum will form.
