FunFam 19: Serpin 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 2 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
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.

Cysteine-type endopeptidase inhibitor activity GO:0004869
Stops, prevents or reduces the activity of a cysteine-type endopeptidase, any enzyme that hydrolyzes peptide bonds in polypeptides by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile.

2 Q9VFC1 (/ISM) Q9VFC2 (/ISM)
Response to fungus GO:0009620
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 a stimulus from a fungus.
1 Q9VFC1 (/HEP)
Negative regulation of Toll signaling pathway GO:0045751

1 Q9VFC2 (/IMP)
Imaginal disc-derived wing expansion GO:0048526
The process of expanding or inflating the folded imaginal disc-derived pupal wing, and the adhering of the dorsal and ventral surfaces, to form the mature adult wing.
1 Q9VFC2 (/IMP)
Epithelium regeneration GO:1990399
The regrowth of lost or destroyed epithelium.
