Predicted to enable peptidoglycan binding activity; peptidoglycan immune receptor activity; and protein heterodimerization activity. Predicted to be involved in antimicrobial humoral immune response mediated by antimicrobial peptide; killing of cells of other organism; and response to bacterium. Predicted to act upstream of or within biological process involved in interaction with host; negative regulation of interferon-gamma production; and negative regulation of natural killer cell differentiation involved in immune response. Predicted to be located in extracellular region. Predicted to be part of protein-containing complex. Orthologous to human PGLYRP3 (peptidoglycan recognition protein 3).
