Gene Snapshot
Peptidoglycan recognition protein SB1 (PGRP-SB1) encodes a secreted peptidoglycan recognition protein (PGRP) with an amidase activity against DAP-type peptidoglycan, a cell wall component found on Gram-negative bacteria and certain Gram positive bacteria. It is strongly induced upon bacterial infection by the immune deficiency pathway, suggesting a role as an immune effector. [Date last reviewed: 2019-03-14]

Summaries
Gene Group (FlyBase)
SHORT PEPTIDOGLYCAN RECOGNITION PROTEINS -
Peptidoglycan recognition proteins (PGRPs) are pattern recognition molecules of the innate immune response that bind peptidoglycans. Insect PGRPs can be divided into two groups based on transcript size: short PGRPs (PGRP-S) and long PGRPs (PGRP-L). PGRP-S have signal peptides and can be extracellular proteins. (Adapted from FBrf0223078).
Protein Function (UniProtKB)
N-acetylmuramyl-L-alanine amidase involved in innate immunity by degrading bacterial peptidoglycans (PGN), preferentially DAP-type PGNs. Probably plays a scavenger role by digesting biologically active PGN into biologically inactive fragments.
