GO term | GO name | GO namespace | GO def |
GO:0005634 | nucleus | cellular_component | 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. [GOC:go_curators] |
GO:0006338 | chromatin remodeling | biological_process | Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation. [GOC:jid, GOC:vw, PMID:12042764, PMID:12697820] |
GO:0043228 | non-membrane-bounded organelle | cellular_component | Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane. Includes ribosomes, the cytoskeleton and chromosomes. [GOC:go_curators] |
GO:0003682 | chromatin binding | molecular_function | Binding to chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase. [GOC:jl, ISBN:0198506732, PMID:20404130] |
GO:0007283 | spermatogenesis | biological_process | The developmental process by which male germ line stem cells self renew or give rise to successive cell types resulting in the development of a spermatozoa. [GOC:jid, ISBN:9780878933846, PMID:28073824, PMID:30990821] |
GO:0043232 | intracellular non-membrane-bounded organelle | cellular_component | Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane and occurring within the cell. Includes ribosomes, the cytoskeleton and chromosomes. [GOC:go_curators] |
GO:0009952 | anterior/posterior pattern specification | biological_process | The regionalization process in which specific areas of cell differentiation are determined along the anterior-posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism. [GOC:dph, GOC:go_curators, GOC:isa_complete, GOC:tb] |
GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
GO:0110165 | cellular anatomical entity | cellular_component | A part of a cellular organism that is either an immaterial entity or a material entity with granularity above the level of a protein complex but below that of an anatomical system. Or, a substance produced by a cellular organism with granularity above the level of a protein complex. [GOC:kmv] |
GO:0005654 | nucleoplasm | cellular_component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
GO:0043229 | intracellular organelle | cellular_component | 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. [GOC:go_curators] |
GO:0042393 | histone binding | molecular_function | Binding to a histone, any of a group of water-soluble proteins found in association with the DNA of eukaroytic chromosomes. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in nonspecific suppression of gene activity. [GOC:jl] |
GO:0043226 | organelle | cellular_component | 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. [GOC:go_curators] |
GO:0045892 | negative regulation of transcription, DNA-templated | biological_process | Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription. [GOC:go_curators, GOC:txnOH] |
GO:0031507 | heterochromatin assembly | biological_process | An epigenetic gene silencing mechanism that involves the assembly of chromatin into heterochromatin, resulting in a chromatin conformation refractory to transcription. This process starts with heterochromatin nucleation, its spreading, and ends with heterochromatin boundary formation. [GOC:mah, PMID:25192661, PMID:33827924] |
