GeneID: 107


Common Name: MBL2 Type: Gene
Chromosome: 10 (NC_000010.11) Locus: NG_008196.1 (MBL2)
HUGO Symbol: MBL2 Full Name: mannose binding lectin 2
Exons: 4 Introns: 3

The encoded protein is a mannose-binding lectin (MBL) involved in the innate immune response. It is derived from liver and secreted in plasma, where it binds sugar residues, such as mannose, fucose and N-acetylglucosamine on the surface of pathogens, leading to their opsonization and phagocytosis by specialized immune cells. This protein is able to activate the complement pathway in an antibody-independent manner via cooperation with MBL-associated serine proteases (MASP). MBL also binds and mediates clearance of apoptotic cells and cell debris. Deficiencies of this gene have been associated with susceptibility to autoimmune and infectious diseases. Polymorphisms in this gene associated with vaso-occlusive pain crisis and infection in sickle cell anemia patients.

Synonyms: MBL , COLEC1
