The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:

"
Tetratricopeptide repeat domain

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 4 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
Single-stranded DNA binding GO:0003697
Interacting selectively and non-covalently with single-stranded DNA.
2 P17214 (/IDA) P17214 (/IDA)
RNA binding GO:0003723
Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
2 P17214 (/IPI) P17214 (/IPI)
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).
2 P17214 (/IPI) P17214 (/IPI)
Telomeric DNA binding GO:0042162
Interacting selectively and non-covalently with a telomere, a specific structure at the end of a linear chromosome required for the integrity and maintenance of the end.

There are 5 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.
2 P17214 (/IMP) P17214 (/IMP)
Telomere maintenance via telomerase GO:0007004
The maintenance of proper telomeric length by the addition of telomeric repeats by telomerase.
2 P17214 (/IDA) P17214 (/IDA)
Telomere maintenance via telomerase GO:0007004
The maintenance of proper telomeric length by the addition of telomeric repeats by telomerase.
2 P17214 (/IMP) P17214 (/IMP)
Regulation of telomere maintenance via telomerase GO:0032210
Any process that modulates the frequency, rate or extent of the addition of telomeric repeats by telomerase.
2 P17214 (/IDA) P17214 (/IDA)
G-quadruplex DNA formation GO:0071919
A DNA metabolic process that results in the formation of G-quadruplex DNA structures, in which groups of four guanines adopt a flat, cyclic Hoogsteen hydrogen-bonding arrangement known as a guanine tetrad or G-quartet. The stacking of several layers of G-quartets forms G-quadruplexes, in which one or more DNA single strands are assembled in parallel and/or antiparallel, with interactions that can be either intra- or intermolecular in nature.

There are 3 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 P17214 (/IDA) P17214 (/IDA)
Telomerase holoenzyme complex GO:0005697
Telomerase is a ribonucleoprotein enzyme complex, with a minimal catalytic core composed of a catalytic reverse transcriptase subunit and an RNA subunit that provides the template for telomeric DNA addition. In vivo, the holoenzyme complex often contains additional subunits.
2 P17214 (/IDA) P17214 (/IDA)
Nucleolus GO:0005730
A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.
