FunFam 5846: Cytochrome b5 reductase 4

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 4 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
Cytochrome-b5 reductase activity, acting on NAD(P)H GO:0004128

1 Q7L1T6 (/IDA)
Cytochrome-b5 reductase activity, acting on NAD(P)H GO:0004128
Catalysis of the reaction: NAD(P)H + H+ + 2 ferricytochrome b(5) = NAD(P)+ + 2 ferrocytochrome b(5).
1 Q7L1T6 (/TAS)

GO Term Annotations Evidence
Detection of oxygen GO:0003032
The series of events in which an oxygen stimulus is received by a cell and converted into a molecular signal.
1 Q7L1T6 (/NAS)
Generation of precursor metabolites and energy GO:0006091
The chemical reactions and pathways resulting in the formation of precursor metabolites, substances from which energy is derived, and any process involved in the liberation of energy from these substances.
1 Q7L1T6 (/IDA)
Superoxide metabolic process GO:0006801
The chemical reactions and pathways involving superoxide, the superoxide anion O2- (superoxide free radical), or any compound containing this species.
1 Q7L1T6 (/IDA)
Bicarbonate transport GO:0015701
The directed movement of bicarbonate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
1 Q7L1T6 (/TAS)
Insulin secretion GO:0030073
The regulated release of proinsulin from secretory granules (B granules) in the B cells of the pancreas; accompanied by cleavage of proinsulin to form mature insulin.
1 Q7L1T6 (/ISS)
Glucose homeostasis GO:0042593
Any process involved in the maintenance of an internal steady state of glucose within an organism or cell.
1 Q7L1T6 (/ISS)
Response to antibiotic GO:0046677
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.
1 Q7L1T6 (/ISS)
Cell development GO:0048468
The process whose specific outcome is the progression of the cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to a specific fate.
1 Q7L1T6 (/ISS)
Oxidation-reduction process GO:0055114
A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.

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 Q7L1T6 (/IDA)
Endoplasmic reticulum membrane GO:0005789
The lipid bilayer surrounding the endoplasmic reticulum.
1 Q7L1T6 (/TAS)
Perinuclear region of cytoplasm GO:0048471
