Siglec-2/CD22 Proteins and Enzymes

Siglec-2 (sialic acid binding Ig-like lectin 2), also known as CD22, is a 130-140 kDa type I transmembrane glycoprotein with seven Ig-like domains in the extracellular region and three ITIM motifs in its cytoplasmic region. Alternate splicing generates an additional isoform that lacks the third and fourth Ig-like domains. Siglec-2 is expressed on B...
