Glycan-binding proteins (GBPs) decode information in the mammalian glycome. New tools help identify GBP glycan ligands and understand their functions in biological processes.

Area of Science:

  • Glycobiology
  • Molecular Biology
  • Cell Biology

Background:

  • Glycan-binding proteins (GBPs) are crucial for diverse biological functions, including cell signaling and host-pathogen interactions.
  • Identifying specific glycan ligands and understanding their influence on GBP function remains a significant challenge.
  • Low-affinity protein-glycan interactions often require multivalent binding for biological activity.

Purpose of the Study:

  • To highlight recent advancements in identifying glycan ligands for GBPs.
  • To elucidate the mechanisms underlying GBP function in biological contexts.
  • To address the challenges in understanding the specificity and impact of glycan recognition.

Main Methods:

  • Development and application of advanced glycan arrays.
