Function
Innate immunity protein that plays several important functions in antimicrobial and antitumor defense systems. Acts as a pattern receptor that binds to murein peptidoglycans (PGN) of Gram-positive bacteria and thus provides bactericidal activity (PubMed:9707603). Forms an equimolar complex with heat shock protein HSPA1A and induces programmed cell death through apoptosis and necroptosis in tumor cell lines by activating the TNFR1 receptor on the target cell membrane (PubMed:21247889, PubMed:26183779). In addition, acts in complex with the Ca(2+)-binding protein S100A4 as a chemoattractant able to induce lymphocyte movement (PubMed:26654597). Mechanistically, this complex acts as a ligand of the chemotactic receptors CCR5 and CXCR3 which are present on the cells of the immune system (PubMed:30713770). Promotes also the activation of lymphocytes that become able to kill virus-infected cells as well as tumor cells by modulating the spectrum of their target-cell specificity (PubMed:28977785, PubMed:29083508). Induction of cytotoxicity on monocyte surface requires interaction with TREM1 receptor (PubMed:25595774, PubMed:28977785).

Notes
Human PGRPs ELISA Kit is designed for the quantitative determination of PGRPs in cell culture supernatants, plasma and serum samples.
This assay employs an antibody specific for human PGRPs coated on a 96-well plate. Standards and samples are pipetted into the wells and PGRPs present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-human PGRPs antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of PGRPs bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
This ELISA antibody pair detects human PGRPs, less than 0.05% cross-reactivity with human PGRP-1 beta and mouse PGRPs is observed.

- Activity summary
Peptidoglycan Recognition Proteins (PGRPs) are pattern recognition receptors known for their role in innate immunity. Some alternate names for PGRPs include PGLYRPs. These proteins identify bacterial peptidoglycans triggering immune responses. PGRPs have varying molecular masses that range typically between 20 to 25 kDa. Expression of PGRPs occurs in several tissues including skin eyes liver and throughout the gastrointestinal tract.
- Biological function summary
Functioning in innate immunity PGRPs bind to bacterial cell wall components such as peptidoglycan and lipopolysaccharides. When PGRPs detect these molecules they can activate immune responses to neutralize pathogens. Some PGRPs can also act as amidases breaking down peptidoglycans. PGRPs do not usually act alone; they are part of complexes with other immune proteins to enhance pathogen recognition and response.
- Pathways
PGRPs play significant roles in the immune pathway and inflammatory signaling pathways. They interact with the toll-like receptor pathways to mediate responses to bacterial infections. PGRPs also link with Nod proteins to modulate the immune response upon detecting peptidoglycans. These pathways help coordinate an effective defense against infection.
- Associated diseases and disorders
PGRPs’ malfunction or dysregulation links with inflammatory bowel disease and psoriasis. Altered PGRP levels correlate with changes in the gut flora contributing to inflammatory bowel disease. In psoriasis PGRPs’ improper function may exacerbate skin inflammation because they interact with proteins like IL-6 and TNF-alpha. Such interactions highlight their potential as therapeutic targets for these conditions.
