FunFam 24: Histone H3

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 0 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 3 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
Double fertilization forming a zygote and endosperm GO:0009567
Fertilization where one of the two sperm nuclei from the pollen tube fuses with the egg nucleus to form a 2n zygote, and the other fuses with the two polar nuclei to form the 3n primary endosperm nucleus and then develops into the endosperm. The ploidy level of the 2n zygote and 3n primary endosperm nucleus is determined by the ploidy level of the parents involved. An example of this component is found in Arabidopsis thaliana.
2 Q9FXI7 (/IEP) Q9FXI7 (/IEP)
Response to mercury ion GO:0046689
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a mercury ion stimulus.
2 O15819 (/IDA) Q55BN9 (/IDA)
Pollen sperm cell differentiation GO:0048235
The process in which a relatively unspecialized cell acquires specialized features of a haploid sperm cell within the plant gametophyte.

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.
3 Q55BP0 (/IDA) Q9FXI7 (/IDA) Q9FXI7 (/IDA)
Generative cell nucleus GO:0048555
The nucleus of the generative cell, a cell contained within the pollen grain that will divide to produce two haploid sperm cells.
