antigen processing and presentation of exogenous peptide antigen
|
GO_0002478 |
[The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC protein complex. The peptide is typically a fragment of a larger exogenous protein which has been degraded within the cell.] |

|
GO_0002495 |

mitotic telomere tethering at nuclear periphery
|
GO_0044820 |
[The process in which a telomere is maintained in a specific location at the nuclear periphery, as part of a mitotic cell cycle.] |
protein kinase regulator activity
|
GO_0019887 |
[Modulates the activity of a protein kinase, an enzyme which phosphorylates a protein.] |
kinase regulator activity
|
GO_0019207 |
[Modulates the activity of a kinase, an enzyme which catalyzes of the transfer of a phosphate group, usually from ATP, to a substrate molecule.] |
protein phosphatase regulator activity
|
GO_0019888 |
[Binds to and modulates the activity of a protein phosphatase.] |
phosphatase regulator activity
|
GO_0019208 |

pteridine metabolic process
|
GO_0019889 |
[The chemical reactions and pathways involving pteridine, pyrazino(2,3-dipyrimidine), the parent structure of pterins and the pteroyl group.] |
pteridine-containing compound metabolic process
|
GO_0042558 |
[The chemical reactions and pathways involving any compound containing pteridine (pyrazino(2,3-dipyrimidine)), e.g. pteroic acid, xanthopterin and folic acid.] |
A-type (transient outward) potassium channel activity
|
GO_0005250 |
[Enables the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel that produces a transient outward current upon a step change in membrane potential.] |
outward rectifier potassium channel activity
|
GO_0015271 |
[Enables the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel. An outwardly rectifying current-voltage relation is one where at any given driving force the outward flow of K+ ions exceeds the inward flow for the opposite driving force.] |
delayed rectifier potassium channel activity
|
GO_0005251 |
[Enables the transmembrane transfer of a potassium ion by a delayed rectifying voltage-gated channel. A delayed rectifying current-voltage relation is one where channel activation kinetics are time-dependent, and inactivation is slow.] |
open rectifier potassium channel activity
|
GO_0005252 |
[Enables the transmembrane transfer of a potassium ion by an open rectifier voltage-gated channel. An open rectifier current-voltage relationship is one in which the direction of rectification depends on the external potassium ion concentration.] |
monoatomic anion channel activity
|
GO_0005253 |
[Enables the energy-independent facilitated diffusion of a monoatomic anion through a transmembrane aqueous pore or channel.] |
monoatomic anion transmembrane transporter activity
|
GO_0008509 |
[Enables the transfer of a negatively charged ion from one side of a membrane to the other.] |
chloride transmembrane transporter activity
|
GO_0015108 |
[Enables the transfer of chloride ions from one side of a membrane to the other.] |
heparin biosynthetic process
|
GO_0030210 |
[The chemical reactions and pathways resulting in the formation of heparin, any member of a group of glycosaminoglycans of average Mr (6000-20000), consisting predominantly of alternating alpha-(1->4)-linked D-galactose and N-acetyl-D-glucosamine-6-sulfate residues.] |
glycosaminoglycan biosynthetic process
|
GO_0006024 |
[The chemical reactions and pathways resulting in the formation of glycosaminoglycans, any of a group of polysaccharides that contain amino sugars.] |
heparin metabolic process
|
GO_0030202 |
[The chemical reactions and pathways involving heparin, any member of a group of glycosaminoglycans found mainly as an intracellular component of mast cells. They are similar to heparan sulfates but are of somewhat higher average Mr (6000-20000) and contain fewer N-acetyl groups and more N-sulfate and O-sulfate groups; they may be attached in the same manner to protein, forming proteoglycans. They consist predominantly of alternating alpha-(1->4)-linked D-galactose and N-acetyl-D-glucosamine-6-sulfate residues.] |
sulfur compound biosynthetic process
|
GO_0044272 |
[The chemical reactions and pathways resulting in the formation of compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione.] |
