About MASP1

Cytogenetic location: 3q27.3 Genomic coordinates (GRCh38): 3:187,217,282-187,291,737 (from NCBI)

This gene has 15 transcripts (splice variants), 208 orthologues, 2 paralogues and is associated with 3 phenotypes. Biased expression in liver (RPKM 20.5), endometrium (RPKM 13.2) and 10 other tissues.

Summary

This gene encodes a serine protease that functions as a component of the lectin pathway of complement activation. The complement pathway plays an essential role in the innate and adaptive immune response. The encoded protein is synthesized as a zymogen and is activated when it complexes with the pathogen recognition molecules of lectin pathway, the mannose-binding lectin and the ficolins. This protein is not directly involved in complement activation but may play a role as an amplifier of complement activation by cleaving complement C2 or by activating another complement serine protease, MASP-2. The encoded protein is also able to cleave fibrinogen and factor XIII and may may be involved in coagulation. A splice variant of this gene which lacks the serine protease domain functions as an inhibitor of the complement pathway. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Apr 2010]
