molecular function |
| GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| GO:0098505 | | G-rich strand telomeric DNA binding | | Interacting selectively and non-covalently with G-rich, single-stranded, telomere-associated DNA. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0043047 | | single-stranded telomeric DNA binding | | Interacting selectively and non-covalently with single-stranded telomere-associated DNA. |
| GO:0010521 | | telomerase inhibitor activity | | Stops, prevents or reduces the activity of a telomerase. Telomerase catalyzes the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). Catalyzes extension of the 3'- end of a DNA strand by one deoxynucleotide at a time using an internal RNA template that encodes the telomeric repeat sequence. |
biological process |
| GO:0051974 | | negative regulation of telomerase activity | | Any process that stops or reduces the activity of the enzyme telomerase, which catalyzes of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). |
| GO:0032211 | | negative regulation of telomere maintenance via telomerase | | Any process that stops, prevents, or reduces the frequency, rate or extent of the addition of telomeric repeats by telomerase. |
| GO:0016233 | | telomere capping | | 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. |
| GO:0000723 | | telomere maintenance | | 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. |
cellular component |
| GO:0005694 | | chromosome | | A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. |
| GO:0000781 | | chromosome, telomeric region | | The terminal region of a linear chromosome that includes the telomeric DNA repeats and associated proteins. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0000784 | | nuclear chromosome, telomeric region | | The terminal region of a linear nuclear chromosome that includes the telomeric DNA repeats and associated proteins. |
| GO:0000783 | | nuclear telomere cap complex | | A complex of DNA and protein located at the end of a linear chromosome in the nucleus that protects and stabilizes a linear chromosome. |
| GO:0005724 | | nuclear telomeric heterochromatin | | Heterochromatic regions of the chromosome found at the telomeres of a chromosome in the nucleus. |
| GO:0005634 | | nucleus | | 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. |
| GO:0070187 | | shelterin complex | | 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 Schizosaccharomyces. 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. |
