Peptidoglycan-recognition protein LE

UniProtKB accession:  Q9VXN9

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Peptidoglycan-recognition protein that plays a key role in innate immunity by binding to murein peptidoglycans (PGN) of Gram-negative bacteria and activating the imd/Relish pathway. Has no activity against on Gram-positive bacteria. Binds to diaminopimelic acid-type PGN (DAP-type PGN), an activator of the imd/Relish pathway. Functions synergistically with PGRP-LC in producing resistance to E.coli and B.megaterium infections, which have the DAP-type peptidoglycan. Acts both upstream and in parallel with PGRP-LC in the imd/Relish pathway, and is required for infection-dependent activation of melanization. Required for Relish processing and nuclear translocation following proteolytic cleavage. Its localization suggests a role in the recognition and subsequent activation of the signaling at the first point of contact with invading bacteria.
