Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

Any process in which a protein is transported to, and/or maintained in, a specific location at the level of a cell. Localization at the cellular level encompasses movement within the cell, from within the cell to the cell surface, or from one location to another at the surface of a cell.

Repression of transcription of ribosomal DNA by altering the structure of chromatin.

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.

Repression of transcription of telomeric DNA by altering the structure of chromatin.

The process that determines which donor locus a cell uses, in preference to another, in mating type switching.

Repression of transcription at silent mating-type loci by alteration of the structure of chromatin.

Repression of transcription of centromeric DNA by altering the structure of chromatin.

Repression of transcription of centromeric DNA by altering the structure of chromatin.

Repression of transcription by conversion of large regions of DNA into heterochromatin, directed by small RNAs sharing sequence identity to the repressed region.

The assembly of chromatin into heterochromatin that is located adjacent to the CENP-A rich centromere 'central core' and characterized by the modified histone H3K9me3.

The cell cycle process in which the dynamic reorganization of telomeres occurs in early meiotic prophase, during which meiotic chromosome ends are gathered in a bouquet arrangement at the inner surface of the nuclear envelope proximal to the spindle pole body. This plays an important role in progression through meiosis and precedes synapsis.

Any process in which a protein is transported to, or maintained at, the centromeric region of a chromosome.

Any heterochromatin maintenance that is involved in chromatin silencing at centromere outer repeat region.

A process in which a protein is transported to, or maintained in, a location within a nuclear pericentric heterochromatin.

A process in which a protein is transported to, or maintained in, a location within a mating-type region heterochromatin.

Repression of transcription of DNA at the outer repeat region of a regional centromere by altering the structure of chromatin.

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.

A protein complex required for heterochromatin assembly; contains an Argonaute homolog, a chromodomain protein, and at least one additional protein; named for RNA-induced initiation of transcriptional gene silencing.

Nuclear heterochromatin that is located adjacent to the CENP-A rich centromere 'central core' and characterized by the modified histone H3K9me3.

Nuclear heterochromatin that is located adjacent to the CENP-A rich centromere 'central core' and characterized by the modified histone H3K9me3.

Heterochromatic regions of the chromosome found at silenced mating-type loci.

Heterochromatic regions of the chromosome found at silenced mating-type loci.

The portion of the centromeric region of a chromosome that flanks the core region, encompassing repeated regions of a chromosome centromere and the proteins that bind to it.

An cullin-dependent E3 ubiquitin ligase/histone H3-K9 methyltransferase complex essential for heterochromatin assembly by RNAi.

Heterochromatic regions of the chromosome found at the subtelomeric regions of a chromosome in the nucleus.

Heterochromatic regions of the chromosome found at the subtelomeric regions of a chromosome in the nucleus.
