FunFam 101: Cyclin, putative

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 1 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.
GO Term Annotations Evidence
Cyclin-dependent protein serine/threonine kinase activator activity GO:0061575
Binds to and increases the activity of a cyclin-dependent protein serine/threonine kinase.
1 O59748 (/IMP)

There are 4 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
Signaling GO:0023052
The entirety of a process in which information is transmitted within a biological system. This process begins with an active signal and ends when a cellular response has been triggered.
1 O59748 (/NAS)
Phosphorylation of RNA polymerase II C-terminal domain serine 2 residues GO:0071619
The process of introducing a phosphate group onto a serine residue at position 2 within the heptapeptide repeat (YSPTSPS) of the C-terminal domain of RNA polymerase II. Typically, phosphorylation of serine 2 (Ser2) occurs subsequent to phosphorylation of serine 5 and is thus seen in the middle and 3' ends of genes. In vivo, Ser2 phosphorylation is primarily performed by CTDK-I in S. cerevisiae or CDK9 in metazoans.
1 O59748 (/IMP)
Positive regulation of induction of conjugation with cellular fusion by regulation of transcription from RNA polymerase II promoter GO:1904788
A regulation of transcription from RNA polymerase II promoter that results in positive regulation of induction of conjugation with cellular fusion.
1 O59748 (/IMP)
Positive regulation of phosphorylation of RNA polymerase II C-terminal domain serine 2 residues GO:2001165
Any process that activates or increases the frequency, rate or extent of phosphorylation of RNA polymerase II C-terminal domain serine 2 residues.
1 O59748 (/IMP)

There are 6 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.
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.
1 O59748 (/HDA)
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.
1 O59748 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 O59748 (/HDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 O59748 (/HDA)
Nuclear cyclin-dependent protein kinase holoenzyme complex GO:0019908
Cyclin-dependent protein kinase (CDK) complex found in the nucleus.
1 O59748 (/IPI)
CTDK-1 complex GO:0070692
A positive transcription elongation factor complex that comprises the CDK kinase CTK1 (in budding yeast), Lsk1 (in fission yeast) (corresponding to the Panther PTHR24056:SF39 family), a cyclin and an additional gamma subunit (corresponding to the InterPRO entry IPR024638).
