Descriptions

Kunitz-type protease inhibitor 2 (or hepatocyte growth factor activator inhibitor type 2 (HAI-2)) is an integral membrane Kunitz-type serine protease inhibitor that regulates the proteolysis of matriptase and prostasin in a cell-type selective manner. The vast majority of non-glycosylated HAI-2 is synthesized into multiple disulfide-linked oligomers, which lack protease inhibitory function, likely due to distorted conformations caused by the disarrayed disulfide linkages. N-glycosylation on Asn-57 is required for folding into a functional HAI-2 with full protease suppressive activity and correct subcellular targeting signal.

2 GO annotations of cellular component

Name Definition
extracellular matrix A structure lying external to one or more cells, which provides structural support, biochemical or biomechanical cues for cells or tissues.
extracellular space That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

2 GO annotations of molecular function

Name Definition
extracellular matrix structural constituent The action of a molecule that contributes to the structural integrity of the extracellular matrix.
serine-type endopeptidase inhibitor activity Binds to and stops, prevents or reduces the activity of a serine-type endopeptidase.

2 GO annotations of biological process

Name Definition
blood coagulation The sequential process in which the multiple coagulation factors of the blood interact, ultimately resulting in the formation of an insoluble fibrin clot; it may be divided into three stages
cellular response to fluid shear stress 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 fluid shear stress stimulus. Fluid shear stress is the force acting on an object in a system where the fluid is moving across a solid surface.
