FunFam 39170: Interleukin-31 receptor subunit alpha

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 2 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
Cytokine receptor activity GO:0004896
Combining with a cytokine and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.
1 Q8K5B1 (/ISO)
Cytokine binding GO:0019955
Interacting selectively and non-covalently with a cytokine, any of a group of proteins that function to control the survival, growth and differentiation of tissues and cells, and which have autocrine and paracrine activity.
1 Q8K5B1 (/IPI)

There are 9 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
Glandular epithelial cell differentiation GO:0002067
The process in which a relatively unspecialized cell acquires specialized features of a glandular epithelial cell. A glandular epithelial cell is a columnar/cuboidal epithelial cell found in a two dimensional sheet with a free surface exposed to the lumen of a gland.
1 Q8K5B1 (/IMP)
Acute inflammatory response to antigenic stimulus GO:0002438
An acute inflammatory response to an antigenic stimulus. An acute inflammatory response occurs within a matter of minutes or hours, and either resolves within a few days or becomes a chronic inflammatory response.
1 Q8K5B1 (/IMP)
JAK-STAT cascade GO:0007259
Any process in which STAT proteins (Signal Transducers and Activators of Transcription) and JAK (Janus Activated Kinase) proteins convey a signal to trigger a change in the activity or state of a cell. The JAK-STAT cascade begins with activation of STAT proteins by members of the JAK family of tyrosine kinases, proceeds through dimerization and subsequent nuclear translocation of STAT proteins, and ends with regulation of target gene expression by STAT proteins.
1 Q8K5B1 (/ISS)
Positive regulation of cell proliferation GO:0008284
Any process that activates or increases the rate or extent of cell proliferation.
1 Q8K5B1 (/ISO)
Positive regulation of cell proliferation GO:0008284
Any process that activates or increases the rate or extent of cell proliferation.
1 Q8K5B1 (/ISS)
Monocyte differentiation GO:0030224
The process in which a relatively unspecialized myeloid precursor cell acquires the specialized features of a monocyte.
1 Q8K5B1 (/ISS)
T-helper 2 cell cytokine production GO:0035745
Any process that contributes to cytokine production by a T-helper 2 cell.
1 Q8K5B1 (/IMP)
Positive regulation of tyrosine phosphorylation of STAT protein GO:0042531
Any process that activates or increases the frequency, rate or extent of the introduction of a phosphate group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.
1 Q8K5B1 (/ISS)
Defense response to other organism GO:0098542
Reactions triggered in response to the presence of another organism that act to protect the cell or organism from damage caused by that organism.
1 Q8K5B1 (/IMP)

There are 2 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
External side of plasma membrane GO:0009897
The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.
1 Q8K5B1 (/IDA)
Integral component of membrane GO:0016021
The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
