FunFam 13: Structural maintenance of chromosomes protein 3

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
Chromatin binding GO:0003682
Interacting selectively and non-covalently with chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase.
1 Q56YN8 (/IDA)
Protein heterodimerization activity GO:0046982
Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer.
1 Q552D9 (/ISS)

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
Regulation of DNA replication GO:0006275
Any process that modulates the frequency, rate or extent of DNA replication.
1 Q552D9 (/ISS)
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 Q56YN8 (/IMP)
Sister chromatid cohesion GO:0007062
The cell cycle process in which the sister chromatids of a replicated chromosome become tethered to each other.
1 Q56YN8 (/IMP)
Mitotic sister chromatid cohesion GO:0007064
The cell cycle process in which the sister chromatids of a replicated chromosome are joined along the entire length of the chromosome, from their formation in S phase through metaphase during a mitotic cell cycle. This cohesion cycle is critical for high fidelity chromosome transmission.
1 Q552D9 (/ISS)

There are 12 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 Q56YN8 (/IDA) Q57UB5 (/IDA)
Cohesin complex GO:0008278
A protein complex that is required for sister chromatid cohesion in eukaryotes. The cohesin complex forms a molecular ring complex, and is composed of structural maintenance of chromosomes (SMC) and kleisin proteins. For example, in yeast, the complex is composed of the SMC proteins Smc1p and Smc3p, and the kleisin protein Scc1p. In vertebrates, the complex is composed of the SMC1 (SMC1A or SMC1B) and SMC3 heterodimer attached via their hinge domains to a kleisin (RAD21, REC8 or RAD21L) which links them, and one STAG protein (STAG1, STAG2 or STAG3).
2 Q552D9 (/ISS) Q56YN8 (/ISS)
Chromatin GO:0000785
The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome.
1 Q56YN8 (/IDA)
Chromatin GO:0000785
The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome.
1 Q552D9 (/ISS)
Nuclear chromatin GO:0000790
The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome in the nucleus.
1 B2FDA8 (/IDA)
Nucleus GO:0005634

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 Q552D9 (/ISS)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q56YN8 (/IDA)
Spindle GO:0005819
The array of microtubules and associated molecules that forms between opposite poles of a eukaryotic cell during mitosis or meiosis and serves to move the duplicated chromosomes apart.
1 Q56YN8 (/IDA)
