Sialic Acid-Containing Receptor (Sia Receptor)

Target
Sia Receptor
Molecular classification
Glycoprotein, Glycolipid, Receptor
01

Overview

Sialic acid-containing receptors are glycan structures present on the surface of vertebrate cells, most abundantly at the terminal positions of glycoproteins and glycolipids. They mediate cell–cell interactions, modulate immune responses via interactions with Siglecs, and serve as attachment points for various pathogens, including viruses, bacteria, and parasites. Structural diversity in linkage types and modifications contributes to their functional specificity. They are important therapeutic targets, especially in the context of viral infections.
