The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:

"
Pancreatic trypsin inhibitor Kunitz domain

FunFam 3302: Kunitz-type protease inhibitor 1

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.
1 Q4V8Q2 (/IMP)
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.

There are 8 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
Neural tube closure GO:0001843
The last step in the formation of the neural tube, where the paired neural folds are brought together and fuse at the dorsal midline.
1 Q9R097 (/IGI)
Embryonic placenta development GO:0001892
The embryonically driven process whose specific outcome is the progression of the placenta over time, from its formation to the mature structure. The placenta is an organ of metabolic interchange between fetus and mother, partly of embryonic origin and partly of maternal origin.
1 Q9R097 (/IMP)
Extracellular matrix organization GO:0030198
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.
1 Q9R097 (/IMP)
Positive regulation of glial cell differentiation GO:0045687
Any process that activates or increases the frequency, rate or extent of glia cell differentiation.
1 Q4V8Q2 (/IMP)
Branching involved in labyrinthine layer morphogenesis GO:0060670
The process in which the branches of the fetal placental villi are generated and organized. The villous part of the placenta is called the labyrinth layer.
1 Q9R097 (/IMP)
Placenta blood vessel development GO:0060674
The process whose specific outcome is the progression of a blood vessel of the placenta over time, from its formation to the mature structure.
1 Q9R097 (/IMP)
Cellular response to BMP stimulus GO:0071773
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a bone morphogenetic protein (BMP) stimulus.
1 Q4V8Q2 (/IEP)
Negative regulation of neural precursor cell proliferation GO:2000178
Any process that stops, prevents, or reduces the frequency, rate or extent of neural precursor cell proliferation.
1 Q4V8Q2 (/IMP)

There are 7 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
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
2 Q4V8Q2 (/IDA) Q9R097 (/IDA)
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.
1 O43278 (/TAS)
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.
1 O43278 (/IDA)
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.
1 Q9R097 (/ISO)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
1 O43278 (/TAS)
Extracellular exosome GO:0070062
A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
1 O43278 (/IDA)
Extracellular exosome GO:0070062
A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
