NCIt definition : Mannan-binding lectin serine protease 2 (686 aa, 76 kDa) is encoded by the human
MASP2 gene. This protein plays a role in the cleavage of complement components C2
and C4.;
NCIt note : An alternative spliced transcript produces a C-terminally truncated active form called
Mannose-binding lectin associated protein 19 (Map19, small MBL-associated protein,
sMAP).; Upon mannan-binding lectin binding, the mannan-binding lectin serine protease 2 preproprotein
is autoproteolytically cleaved C-terminal to the arginine at position 444. This generates
A and B chains that heterodimerize via at least one interchain disulfide bond to form
the mature protease. (UniProt);
