Background: Siglec-5/Siglec-14

Siglecs (Sialic acid binding Ig-like Lectins) are a subgroup of the immunoglobulin superfamily that interact with sialic acids in glycoproteins and glycolipids. Siglec-5, also known as CD170, binds to alpha-2,3- and alpha-2,6-linked sialic acid with similar affinity. It occurs as a disulfide-linked dimer of approximately 140 kDa with the highest expression levels in monocytes and neutrophils. Siglec-5 has an inhibitory motif within its cytoplasmic domain. Siglec-14 is an activating receptor that shares 99.5% aa sequence identity with Siglec-5 through the first two extracellular Ig domains and displays a similar glycan binding preference.
