FunFam 75: Like heterochromatin protein (LHP1)

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 6 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.

There are 12 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
Chromatin organization GO:0006325
Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin.
2 Q946J8 (/IMP) Q946J8 (/IMP)
Chromatin silencing GO:0006342
Repression of transcription by altering the structure of chromatin, e.g. by conversion of large regions of DNA into an inaccessible state often called heterochromatin.

Chromatin silencing GO:0006342
Repression of transcription by altering the structure of chromatin, e.g. by conversion of large regions of DNA into an inaccessible state often called heterochromatin.
2 Q946J8 (/IMP) Q946J8 (/IMP)
Photoperiodism GO:0009648
Any process that results in a change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of detection of, or exposure to, a period of light or dark of a given length, measured relative to a particular duration known as the 'critical day length'. The critical day length varies between species.
2 Q946J8 (/IMP) Q946J8 (/IMP)
Multidimensional cell growth GO:0009825
The process in which a cell irreversibly increases in size in two or three
2 Q946J8 (/IMP) Q946J8 (/IMP)
Negative regulation of flower development GO:0009910
Any process that stops, prevents, or reduces the frequency, rate or extent of flower development.
2 Q946J8 (/IMP) Q946J8 (/IMP)
Shoot system morphogenesis GO:0010016
The process in which the anatomical structures of the shoot are generated and organized. The shoot is the part of a seed plant body that is usually above ground.
2 Q946J8 (/IMP) Q946J8 (/IMP)
Vernalization response GO:0010048
The process of thermal induction in plants in which flowering is promoted by exposure to low temperatures.
2 Q946J8 (/IMP) Q946J8 (/IMP)
Negative regulation of gene expression, epigenetic GO:0045814
Any epigenetic process that stops, prevents or reduces the rate of gene expression.
2 Q946J8 (/IMP) Q946J8 (/IMP)
Negative regulation of molecular function, epigenetic GO:0045857
Any heritable epigenetic process that stops, prevents, or reduces the frequency, rate or extent of protein function by self-perpetuating conformational conversions of normal proteins in healthy cells. This is distinct from, though mechanistically analogous to, disease states associated with prion propagation and amyloidogenesis. A single protein, if it carries a glutamine/asparagine-rich ('prion') domain, can sometimes stably exist in at least two distinct physical states, each associated with a different phenotype; propagation of one of these traits is achieved by a self-perpetuating change in the protein from one form to the other, mediated by conformational changes in the glutamine/asparagine-rich domain. Prion domains are both modular and transferable to other proteins, on which they can confer a heritable epigenetic alteration of function; existing bioinformatics data indicate that they are rare in non-eukarya, but common in eukarya.
2 Q946J8 (/IMP) Q946J8 (/IMP)
Negative regulation of transcription, DNA-templated GO:0045892
Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
2 Q946J8 (/IDA) Q946J8 (/IDA)
Photoperiodism, flowering GO:0048573
A change from the vegetative to the reproductive phase as a result of detection of, or exposure to, a period of light or dark of a given length. The length of the period of light or dark required to initiate the change is set relative to a particular duration known as the 'critical day length'. The critical day length varies between species.

There are 4 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.

Euchromatin GO:0000791
A dispersed and relatively uncompacted form of chromatin.
2 Q946J8 (/IDA) Q946J8 (/IDA)
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 Q946J8 (/IDA) Q946J8 (/IDA)
Nuclear heterochromatin GO:0005720
A condensed form of chromatin, occurring in the nucleus during interphase, that stains strongly with basophilic dyes. The DNA of heterochromatin is typically replicated at a later stage in the cell-division cycle than euchromatin.
2 Q946J8 (/IDA) Q946J8 (/IDA)
Chloroplast GO:0009507
A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.
