Gene: MBL2 (mannose binding lectin 2) Homo sapiens
Symbol: MBL2
Name: mannose binding lectin 2
CRRD ID: 735547
Description: Exhibits calcium-dependent protein binding activity; mannose binding activity; and signaling receptor binding activity. Involved in complement activation, lectin pathway; defense response to Gram-positive bacterium; and negative regulation of viral process. Localizes to extracellular space. Implicated in several diseases, including autoimmune disease (multiple); bacterial infectious disease (multiple); fungal infectious disease (multiple); liver disease (multiple); and lung disease (multiple). Biomarker of several diseases, including Legionnaires' disease; autoimmune disease (multiple); coccidioidomycosis; liver disease (multiple); and lung disease (multiple).
Type: protein-coding
RefSeq Status: REVIEWED

NCBI Annotation Information: Note: MBP (Gene ID: 4155) and MBL2 (Gene ID: 4153) share the MBP symbol/alias in common. MBP is a widely used alternative name for mannose binding lectin 2 (MBL2), which can be confused with the official symbol for MBP (myelin basic protein, GeneID 4155). [01 Jun 2018]; Note: This gene has been reviewed for its involvement in coronavirus biology, and is involved in immune response or antiviral activity.
