All terms in GO

Label	Id	Description
peptidase inhibitor activity	GO_0030414	[Stops, prevents or reduces the activity of a peptidase, any enzyme that catalyzes the hydrolysis peptide bonds.]
serine-type endopeptidase inhibitor activity	GO_0004867	[Stops, prevents or reduces the activity of serine-type endopeptidases, enzymes that catalyze the hydrolysis of nonterminal peptide bonds in a polypeptide chain; a serine residue (and a histidine residue) are at the active center of the enzyme.]
serine-type endopeptidase activity	GO_0004252	[Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine).]
obsolete serpin	GO_0004868	[OBSOLETE. A superfamily of proteins, many of which inhibit serine proteinases and exhibit a high degree of homology with classical serine proteinase inhibitors such as alpha1-antitrypsin or antithrombin.]
GO_0004870	GO_0004870
obsolete signal transducer activity	GO_0004871	[OBSOLETE. 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.]
GO_0004872	GO_0004872
asialoglycoprotein receptor activity	GO_0004873	[Receiving an asialoglycoprotein, and delivering the asialoglycoprotein into the cell via endocytosis. An asialoglycoprotein is a plasma glycoproteins from which the terminal sialic acid residue on their complex carbohydrate groups has been removed. The asialoglycoprotein receptor recognizes the terminal galactose and N-acetylgalactosamine units of the asialoglycoprotein, the receptor-ligand complex is internalized and transported to a sorting organelle where disassociation occurs before the receptor is recycled to the cell membrane.]
obsolete aryl hydrocarbon receptor activity	GO_0004874	[OBSOLETE. Combining with an aryl hydrocarbon and transmitting the signal to initiate a change in cell activity. The aryl hydrocarbon receptor is a ligand-activated transcription factor which translocates to the nucleus to activate transcription upon ligand-binding.]
complement receptor activity	GO_0004875	[Combining with any component or product of the complement cascade and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.]
complement binding	GO_0001848	[Interacting selectively and non-covalently with any component or product of the complement cascade.]
complement receptor mediated signaling pathway	GO_0002430	[A series of molecular signals generated as a consequence of a component of the complement pathway binding to a complement receptor. Such components include both whole complement proteins and fragments of complement proteins generated through the activity of the complement pathway.]
complement component C3a receptor activity	GO_0004876	[Combining with the C3a product of the complement cascade and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.]
complement component C3b receptor activity	GO_0004877	[Combining with the C3b product of the complement cascade and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.]
opsonin receptor activity	GO_0001847	[Combining with an opsonin and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.]
complement component C3b binding	GO_0001851	[Interacting selectively and non-covalently with the C3b product of the complement cascade.]
complement component C3a binding	GO_0001850	[Interacting selectively and non-covalently with the C3a product of the complement cascade.]
complement component C5a receptor activity	GO_0004878	[Combining with the C5a product of the complement cascade and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.]
complement component C5a binding	GO_0001856	[Interacting selectively and non-covalently with the C5a product of the complement cascade.]
complement component C5a signaling pathway	GO_0038178	[A series of molecular signals generated as a consequence of a the C5a component of the complement pathway binding to a complement receptor, and ending with regulation of a downstream cellular process. C5a is a peptide derived from the C5 complement factor.]
