FunFam 1448: Guanine nucleotide-binding protein alpha-5 subunit

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
Signal transducer activity GO:0004871
Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.
1 Q04665 (/IMP)
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 Q04665 (/IPI)
GTP binding GO:0005525
Interacting selectively and non-covalently with GTP, guanosine triphosphate.

There are 10 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 transcription from RNA polymerase II promoter GO:0000122
Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter.
1 Q04665 (/IMP)
Adenylate cyclase-activating G-protein coupled receptor signaling pathway GO:0007189
The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand, where the pathway proceeds through activation of adenylyl cyclase activity and a subsequent increase in the concentration of cyclic AMP (cAMP).
1 Q04665 (/IPI)
Glucose mediated signaling pathway GO:0010255
The process in which a change in the level of mono- and disaccharide glucose trigger the expression of genes controlling metabolic and developmental processes.
1 Q04665 (/IC)
Adenylate cyclase-activating glucose-activated G-protein coupled receptor signaling pathway GO:0010619
The series of molecular signals generated as a consequence of glucose binding to a G-protein coupled receptor, where the pathway proceeds with activation of adenylyl cyclase and a subsequent increase in the concentration of cyclic AMP (cAMP).
1 Q04665 (/IMP)
Positive regulation of cAMP biosynthetic process GO:0030819
Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of the nucleotide cAMP (cyclic AMP, adenosine 3',5'-cyclophosphate).
1 Q04665 (/IMP)
Positive regulation of cAMP-mediated signaling GO:0043950
Any process which activates, maintains or increases the frequency, rate or extent of cAMP-mediated signaling, a series of molecular signals in which a cell uses cyclic AMP to convert an extracellular signal into a response.
1 Q04665 (/IMP)
Negative regulation of transcription by glucose GO:0045014
Any process involving glucose that stops, prevents or reduces the rate of transcription. The presence of glucose in the growth medium inhibits the synthesis of certain enzymes in bacteria growing on the medium. For example, transcription of some catabolic operons is under negative control by specific repressors and glucose is an anti-inducer of xylose utilization and glycerol kinase.
1 Q04665 (/IMP)
Detection of glucose GO:0051594
The series of events in which a glucose stimulus is received by a cell and converted into a molecular signal.
1 Q04665 (/IMP)
Signal transduction involved in regulation of aerobic respiration GO:1903759
Any signal transduction that is involved in regulation of aerobic respiration.
1 Q04665 (/IMP)
Positive regulation of cAMP-dependent protein kinase activity GO:2000481
Any process that activates or increases the frequency, rate or extent of cAMP-dependent protein kinase activity.

There are 8 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 Q04665 (/IDA)
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 Q04665 (/IDA)
Heterotrimeric G-protein complex GO:0005834
Any of a family of heterotrimeric GTP-binding and hydrolyzing proteins; they belong to a superfamily of GTPases that includes monomeric proteins such as EF-Tu and RAS. Heterotrimeric G-proteins consist of three subunits; the alpha subunit contains the guanine nucleotide binding site and possesses GTPase activity; the beta and gamma subunits are tightly associated and function as a beta-gamma heterodimer; extrinsic plasma membrane proteins (cytoplasmic face) that function as a complex to transduce signals from G-protein coupled receptors to an effector protein.
1 Q04665 (/IDA)
Axon GO:0030424
The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.
1 Q20701 (/IDA)
Cell division site GO:0032153
The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. In Eukaryotes, the cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane, and the mitotic, or meiotic, spindle is aligned perpendicular to the division plane. In bacteria, the cell division site is generally located at mid-cell and is the site at which the cytoskeletal structure, the Z-ring, assembles.
1 Q04665 (/IDA)
Neuronal cell body GO:0043025
The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.
1 Q20701 (/IDA)
Mitotic spindle pole body GO:0044732
The microtubule organizing center that forms as part of the mitotic cell cycle; functionally homologous to the animal cell centrosome.
1 Q04665 (/IDA)
Synapse GO:0045202
The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
