CC   -!- FUNCTION: Peptidoglycan-recognition protein probably involved in innate
CC       immunity by binding to peptidoglycans (PGN) of bacteria and activating
CC       the prophenoloxidase (proPO) cascade immune response. Binds to 1,3-
CC       beta-D-glucan and PGN. {ECO:0000269|PubMed:14583608}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:14583608}.
CC   -!- TISSUE SPECIFICITY: Localizes to plasma (at protein level).
CC       {ECO:0000269|PubMed:14583608}.
CC   -!- SIMILARITY: Belongs to the N-acetylmuramoyl-L-alanine amidase 2 family.
CC       {ECO:0000305}.
