FunFam 37: Phosphatidylinositol 3-kinase regulatory subunit b...

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 11 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 TermAnnotationsEvidence
Cellular glucose homeostasis GO:0001678
A cellular homeostatic process involved in the maintenance of an internal steady state of glucose within a cell or between a cell and its external environment.
3 O00459 (/ISS) P23726 (/ISS) Q63788 (/ISS)
Regulation of autophagy GO:0010506
Any process that modulates the frequency, rate or extent of autophagy. Autophagy is the process in which cells digest parts of their own cytoplasm.
3 O08908 (/ISS) P23726 (/ISS) Q63788 (/ISS)
Phosphatidylinositol 3-kinase signaling GO:0014065
A series of reactions within the signal-receiving cell, mediated by the intracellular phosphatidylinositol 3-kinase (PI3K). Many cell surface receptor linked signaling pathways signal through PI3K to regulate numerous cellular functions.
3 O08908 (/ISS) P23726 (/ISS) Q63788 (/ISS)
Cellular response to insulin stimulus GO:0032869
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an insulin stimulus. Insulin is a polypeptide hormone produced by the islets of Langerhans of the pancreas in mammals, and by the homologous organs of other organisms.
3 O00459 (/ISS) P23726 (/ISS) Q63788 (/ISS)
Response to endoplasmic reticulum stress GO:0034976
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stress acting at the endoplasmic reticulum. ER stress usually results from the accumulation of unfolded or misfolded proteins in the ER lumen.
3 O00459 (/ISS) P23726 (/ISS) Q63788 (/ISS)
Positive regulation of protein import into nucleus GO:0042307
Any process that activates or increases the frequency, rate or extent of movement of proteins from the cytoplasm into the nucleus.
3 O00459 (/ISS) P23726 (/ISS) Q63788 (/ISS)
Positive regulation of transcription by RNA polymerase II GO:0045944

GO TermAnnotationsEvidence
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 O00459 (/ISS) P23726 (/ISS) Q63788 (/ISS)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
2 O00459 (/TAS) Q63788 (/TAS)
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.
