FunFam 98: Serine protease inhibitor (Serpin-2)

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.
2 Q9U1I7 (/ISS) Q9VLQ7 (/ISS)
Hormone binding GO:0042562
Interacting selectively and non-covalently with any hormone, naturally occurring substances secreted by specialized cells that affect the metabolism or behavior of other cells possessing functional receptors for the hormone.
2 Q9U1I7 (/ISS) Q9VLQ7 (/ISS)

There are 3 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
Multicellular organism reproduction GO:0032504
The biological process in which new individuals are produced by one or two multicellular organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
2 Q9U1I7 (/HEP) Q9VLQ7 (/HEP)
Multicellular organism reproduction GO:0032504
The biological process in which new individuals are produced by one or two multicellular organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
2 Q9U1I7 (/IEP) Q9VLQ7 (/IEP)
Negative regulation of proteolysis GO:0045861
Any process that stops, prevents, or reduces the frequency, rate or extent of the hydrolysis of a peptide bond or bonds within a protein.
2 Q9U1I7 (/ISS) Q9VLQ7 (/ISS)

There are 3 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
Extracellular region GO:0005576
The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
2 Q9U1I7 (/ISM) Q9VLQ7 (/ISM)
Extracellular space GO:0005615
That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
2 Q9U1I7 (/HDA) Q9VLQ7 (/HDA)
Extracellular space GO:0005615
That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
