Target

Full Name
Mannan Binding Lectin Serine Peptidase 2
Function
Serum protease that plays an important role in the activation of the complement system via mannose-binding lectin. After activation by auto-catalytic cleavage it cleaves C2 and C4, leading to their activation and to the formation of C3 convertase.
Biological Process
Cell surface pattern recognition receptor signaling pathway Source: ComplexPortal
Complement activation, classical pathway Source: UniProtKB-KW
Complement activation, lectin pathway Source: ComplexPortal
Positive regulation of opsonization Source: ComplexPortal
Proteolysis Source: ComplexPortal
Cellular Location
Secreted
Involvement in disease
MASP2 deficiency (MASPD):
A disorder that results in autoimmune manifestations, recurrent severe infections, and chronic inflammatory disease.
PTM
The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.
Activated by cleavage after Arg-444. The uncleaved zymogen is inactive towards synthetic substrates, but has sufficient activity to effect autocatalytic cleavage.
