FunFam 303: Protection of telomeres protein 1
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 3 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 | O13988 (/IPI) |
|
Single-stranded telomeric DNA binding GO:0043047
Interacting selectively and non-covalently with single-stranded telomere-associated DNA.

1 | O13988 (/IDA) |
|
G-rich strand telomeric DNA binding GO:0098505
Interacting selectively and non-covalently with G-rich, single-stranded, telomere-associated DNA.

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 | O13988 (/IMP) |
|
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 | Q7Z862 (/IMP) |
|
Regulation of mitotic nuclear division GO:0007088
Any process that modulates the frequency, rate or extent of mitosis.
|
1 | Q7Z862 (/IMP) |
|
Telomere capping GO:0016233
A process in which telomeres are protected from degradation and fusion, thereby ensuring chromosome stability by protecting the ends from both degradation and from being recognized as damaged DNA. May be mediated by specific single- or double-stranded telomeric DNA binding proteins.
|
1 | O13988 (/IDA) |
|
Telomere capping GO:0016233
A process in which telomeres are protected from degradation and fusion, thereby ensuring chromosome stability by protecting the ends from both degradation and from being recognized as damaged DNA. May be mediated by specific single- or double-stranded telomeric DNA binding proteins.
|
1 | O13988 (/IMP) |
|
Negative regulation of telomere maintenance via telomerase GO:0032211
Any process that stops, prevents, or reduces the frequency, rate or extent of the addition of telomeric repeats by telomerase.
|
1 | O13988 (/IMP) |
There are 6 GO terms relating to "cellular component"

|
Telomere cap complex GO:0000782
A complex of DNA and protein located at the end of a linear chromosome that protects and stabilizes a linear chromosome.
|
1 | O13988 (/IDA) |
|
Nuclear chromosome, telomeric region GO:0000784
The terminal region of a linear nuclear chromosome that includes the telomeric DNA repeats and associated proteins.
|
1 | O13988 (/IDA) |
|
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 | O13988 (/HDA) |
|
Nuclear telomeric heterochromatin GO:0005724
Heterochromatic regions of the chromosome found at the telomeres of a chromosome in the nucleus.
|
1 | O13988 (/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.
|
1 | O13988 (/HDA) |
|
Shelterin complex GO:0070187
A nuclear telomere cap complex that is formed by the association of telomeric ssDNA- and dsDNA-binding proteins with telomeric DNA, and is involved in telomere protection and recruitment of telomerase. The complex is known to contain TERF1, TERF2, POT1, RAP1, TINF2 and ACD in mammalian cells, and Pot1, Tpz1, Rap1, Rif1, Rif2 and Taz1 in Saccharomyces. Taz1 and Rap1 (or their mammalian equivalents) form a dsDNA-binding subcomplex, Pot1 and Tpz1 form an ssDNA-binding subcomplex, and the two subcomplexes are bridged by Poz1, which acts as an effector molecule along with Ccq1.
