Predicted to enable N-acetylmuramoyl-L-alanine amidase activity; peptidoglycan binding activity; and peptidoglycan immune receptor activity. Predicted to be involved in defense response to Gram-positive bacterium and detection of bacterium. Predicted to act upstream of or within several processes, including negative regulation of interferon-gamma production; negative regulation of natural killer cell differentiation involved in immune response; and regulation of inflammatory response. Orthologous to human PGLYRP2 (peptidoglycan recognition protein 2). [provided by Alliance of Genome Resources, Apr 2022]
