MBL: Proteins and Enzymes

Mannose/mannan-binding lectin (MBL) is a secreted glycoprotein in the collectin family of pattern-recognition molecules. It contains a cysteine-rich region, a collagen-like segment, and a C-type lectin domain that binds to neutral bacterial carbohydrates. The collagen-like region mediates MBL association into disulfide-stabilized trimers which further associate into complexes containing three or four copies of the basic trimer. MBL is secreted by hepatocytes and opsonizes bacteria through ...
