Sialic acid function
WebNov 17, 2015 · Sialic acid analogues containing unnatural functional groups can be metabolically incorporated into cellular sialoglycans, thus allowing labeling, visualization, and functional modulation. Abstract Cell-surface sialic acids are essential in mediating a variety of physiological and pathological processes. WebThe sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface. In the immune response, may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatase(s) via their SH2 domain(s) that block signal transduction through dephosphorylation of signaling molecules
