Predicted to enable several functions, including calcium-dependent protein binding activity; identical protein binding activity; and mannose binding activity. Acts upstream of or within defense response to other organism and positive regulation of phagocytosis. Located in extracellular space. Is expressed in embryo. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); bacterial infectious disease (multiple); fungal infectious disease (multiple); liver disease (multiple); and lung disease (multiple). Orthologous to human MBL2 (mannose binding lectin 2). [provided by Alliance of Genome Resources, Apr 2022]
