FunFam 1691: interleukin-27 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 3 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
Transmembrane signaling receptor activity GO:0004888
Combining with an extracellular or intracellular signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity or state as part of signal transduction.
1 Q6UWB1 (/TAS)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 O70394 (/IPI)
Interleukin-27 receptor activity GO:0045509
Combining with interleukin-27 and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.
1 O70394 (/IDA)

There are 15 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
Negative regulation of cellular extravasation GO:0002692
Any process that stops, prevents, or reduces the frequency, rate, or extent of cellular extravasation.
1 O70394 (/IGI)
Positive regulation of T-helper 1 type immune response GO:0002827
Any process that activates or increases the frequency, rate, or extent of a T-helper 1 type immune response.
1 O70394 (/IMP)
Negative regulation of type 2 immune response GO:0002829
Any process that stops, prevents, or reduces the frequency, rate, or extent of a type 2 immune response.
1 O70394 (/IMP)
Immune response GO:0006955
Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.
1 Q6UWB1 (/TAS)
Cell surface receptor signaling pathway GO:0007166
A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription.
1 Q6UWB1 (/TAS)
Positive regulation of interferon-gamma production GO:0032729
Any process that activates or increases the frequency, rate, or extent of interferon-gamma production. Interferon-gamma is also known as type II interferon.
1 O70394 (/IMP)
Regulation of isotype switching to IgG isotypes GO:0048302
Any process that modulates the frequency, rate or extent of isotype switching to IgG isotypes.
1 O70394 (/IMP)
Defense response to Gram-positive bacterium GO:0050830
Reactions triggered in response to the presence of a Gram-positive bacterium that act to protect the cell or organism.
1 O70394 (/IMP)
Interleukin-27-mediated signaling pathway GO:0070106
A series of molecular signals initiated by the binding of interleukin-27 to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.
1 Q6UWB1 (/TAS)
Interleukin-35-mediated signaling pathway GO:0070757
A series of molecular signals initiated by the binding of interleukin-35 to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.
1 Q6UWB1 (/TAS)
Negative regulation of interleukin-6 secretion GO:1900165
Any process that stops, prevents or reduces the frequency, rate or extent of interleukin-6 secretion.
1 O70394 (/IGI)
Negative regulation of tumor necrosis factor secretion GO:1904468
Any process that stops, prevents or reduces the frequency, rate or extent of tumor necrosis factor secretion.
1 O70394 (/IGI)
Negative regulation of interleukin-17 secretion GO:1905077
Any process that stops, prevents or reduces the frequency, rate or extent of interleukin-17 secretion.
1 O70394 (/IGI)
Negative regulation of T-helper 17 type immune response GO:2000317
Any process that stops, prevents or reduces the frequency, rate or extent of T-helper 17 type immune response.
1 O70394 (/IGI)
Negative regulation of T cell extravasation GO:2000408
Any process that stops, prevents or reduces the frequency, rate or extent of T cell extravasation.
