Disease relevance of PGRP-LB

 

High impact information on PGRP-LB

  • (2006) show that PGRP-LB controls systemic immune responses as well as homeostasis at the barrier surfaces [2].
  • Here the crystal structure of Drosophila PGRP-LB is determined at a resolution of 2.0 A and shows an active-site cleft with a zinc cage [3].
  • The serine/histidine juxtaposition to a threonine residue and a carbonyl oxygen atom, along with conservation of the catalytic water molecule found in PGRP-LB, tantalizingly suggests some hydrolytic function for this member of receptor PGRPs [4].
