FunFam 1420: Serine/threonine-protein kinase ppk4

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 5 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.

Endoribonuclease activity GO:0004521
Catalysis of the hydrolysis of ester linkages within ribonucleic acid by creating internal breaks.
1 Q55GJ2 (/ISS)
Protein serine/threonine kinase activity GO:0004674
Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.
1 O94537 (/ISO)
Protein serine/threonine kinase activity GO:0004674
Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.
1 Q55GJ2 (/ISS)
ATP binding GO:0005524
Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.

There are 5 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
Nuclear-transcribed mRNA catabolic process GO:0000956
The chemical reactions and pathways resulting in the breakdown of nuclear-transcribed mRNAs in eukaryotic cells.
1 O94537 (/IMP)
Inositol metabolic process GO:0006020
The chemical reactions and pathways involving inositol, 1,2,3,4,5,6-cyclohexanehexol, a growth factor for animals and microorganisms.
1 Q55GJ2 (/ISS)
Protein phosphorylation GO:0006468
The process of introducing a phosphate group on to a protein.
1 Q55GJ2 (/ISS)
IRE1-mediated unfolded protein response GO:0036498
A series of molecular signals mediated by the endoplasmic reticulum stress sensor IRE1 (Inositol-requiring transmembrane kinase/endonuclease). Begins with activation of IRE1 in response to endoplasmic reticulum (ER) stress, and ends with regulation of a downstream cellular process, e.g. transcription. One target of activated IRE1 is the transcription factor HAC1 in yeast, or XBP1 in mammals; IRE1 cleaves an intron of a mRNA coding for HAC1/XBP1 to generate an activated HAC1/XBP1 transcription factor, which controls the up regulation of UPR-related genes. At least in mammals, IRE1 can also signal through additional intracellular pathways including JNK and NF-kappaB.

GO Term Annotations Evidence
Endoplasmic reticulum GO:0005783
The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
1 O94537 (/HDA)
Endoplasmic reticulum membrane GO:0005789
The lipid bilayer surrounding the endoplasmic reticulum.
1 O94537 (/ISO)
Endoplasmic reticulum membrane GO:0005789
The lipid bilayer surrounding the endoplasmic reticulum.
