This protein enables 2 target(s):

Target	Category	Definition
serine-type endopeptidase activity	molecular function	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).

This protein is located in 5 target(s):

Target	Category	Definition
extracellular region	cellular component	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. [GOC:go_curators]
platelet alpha granule lumen	cellular component	The volume enclosed by the membrane of the platelet alpha granule. [GOC:mah, PMID:8467233]
secretory granule lumen	cellular component	The volume enclosed by the membrane of a secretory granule. [GOC:rph]
extracellular exosome	cellular component	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.

ficolin-1-rich granule lumen	cellular component	Any membrane-enclosed lumen that is part of a ficolin-1-rich granule. [GO_REF:0000064, GOC:TermGenie, PMID:23650620]

This protein is involved in 4 target(s):

Target	Category	Definition
proteolysis	biological process	The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. [GOC:bf, GOC:mah]
complement activation	biological process	Any process involved in the activation of any of the steps of the complement cascade, which allows for the direct killing of microbes, the disposal of immune complexes, and the regulation of other immune processes; the initial steps of complement activation involve one of three pathways, the classical pathway, the alternative pathway, and the lectin pathway, all of which lead to the terminal complement pathway. [GO_REF:0000022, GOC:add, ISBN:0781735149]
complement activation, alternative pathway	biological process	Any process involved in the activation of any of the steps of the alternative pathway of the complement cascade which allows for the direct killing of microbes and the regulation of other immune processes. [GOC:add, ISBN:0781735149]
response to bacterium	biological process	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 bacterium. [GOC:hb]
