Predicted to enable peptidoglycan binding activity; peptidoglycan immune receptor activity; and protein heterodimerization activity. Acts 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. Is expressed in several structures, including adrenal gland; alimentary system; liver; and nervous system. Orthologous to human PGLYRP3 (peptidoglycan recognition protein 3).
