GO Term : GO:0090661 box H/ACA telomerase RNP complex GO

Namespace  cellular_component Obsolete  false
Description  A box H/ACA ribonucleoprotein complex that contains the RNA component of vertebrate telomerase, the enzyme essential for the replication of chromosome termini in most eukaryotes. This ribonucleoprotein complex is a structural box H/ACA RNP, which does not have the catalytic pseudouridylation function shared by the majority of H/ACA RNPs present in the cell.

Identifier Name Description
GO:1902494 catalytic complex A protein complex which is capable of catalytic activity.
GO:0032991 protein-containing complex A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
GO:0005575 cellular_component A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex).
GO:0005622 intracellular anatomical structure A component of a cell contained within (but not including) the plasma membrane. In eukaryotes it includes the nucleus and cytoplasm.
GO:0110165 cellular anatomical structure A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses.
GO:0140513 nuclear protein-containing complex A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together in the nucleus.
GO:0043227 membrane-bounded organelle Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.
GO:0043226 organelle Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane.
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:0043229 intracellular organelle Organized structure of distinctive morphology and function, occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane.
GO:0043231 intracellular membrane-bounded organelle Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.
GO:0005732 sno(s)RNA-containing ribonucleoprotein complex A ribonucleoprotein complex that contains an RNA molecule of the snoRNA family and associated proteins. Many are involved in a step of processing of rRNA molecules: cleavage, 2'-O-methylation, or pseudouridylation, but other RNA types can be targets as well. The majority fall into one of two classes, box C/D type or box H/ACA type, which are conserved across eukaryotes and archaea. Other members include the telomerase RNA and the ribonuclease MRP RNA.
GO:1990904 ribonucleoprotein complex A macromolecular complex that contains both RNA and protein molecules.
GO:0005697 telomerase holoenzyme complex 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.
GO:0072588 box H/ACA RNP complex A ribonucleoprotein complex that contains an RNA of the box H/ACA type and the four core proteins dyskerin, NOP10, NHP2, and GAR1 (human protein nomenclature). RNA pseudouridylation (isomerization of uridine to pseudouridine) is the major, and most likely the ancestral, function of H/ACA RNPs. Pseudouridylation targets include both large and small ribosomal RNAs (rRNAs), and small nuclear RNA (U2 snRNA). In addition to these catalytic H/ACA RNPs, a less abundant but more diverse class of structural H/ACA RNPs exists, which does not have pseudouridylation activity. These include the vertebrate telomerase RNP complex.
GO:0090661 box H/ACA telomerase RNP complex A box H/ACA ribonucleoprotein complex that contains the RNA component of vertebrate telomerase, the enzyme essential for the replication of chromosome termini in most eukaryotes. This ribonucleoprotein complex is a structural box H/ACA RNP, which does not have the catalytic pseudouridylation function shared by the majority of H/ACA RNPs present in the cell.
