Summaries for MASP2 Gene

Entrez Gene Summary for MASP2 Gene

  • This gene encodes a member of the peptidase S1 family of serine proteases. The encoded preproprotein is proteolytically processed to generate A and B chains that heterodimerize to form the mature protease. This protease cleaves complement components C2 and C4 in order to generate C3 convertase in the lectin pathway of the complement system. The encoded protease also plays a role in the coagulation cascade through cleavage of prothrombin to form thrombin. Myocardial infarction and acute stroke patients exhibit reduced serum concentrations of the encoded protein. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

GeneCards Summary for MASP2 Gene

MASP2 (Mannan Binding Lectin Serine Peptidase 2) is a Protein Coding gene. Diseases associated with MASP2 include Masp2 Deficiency and Immunodeficiency Due To Masp-2 Deficiency. Among its related pathways are Immune System and Creation of C4 and C2 activators. GO annotations related to this gene include calcium ion binding and peptidase activity. An important paralog of this gene is HP.

UniProtKB/Swiss-Prot for MASP2 Gene

  • 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.
