背景信息

CD33, also known as sialic acid-binding Ig-like lectin 3 (Siglec-3) or gp67, is a 67-kDa type I transmembrane glycoprotein of sialic acid-binding immunoglobulin-like lactic (Siglec) family, a discrete subset of the immunoglobulin (Ig) superfamily molecules. It contains an amino-terminal V-set Ig-like domain and a C2-set Ig-like domain in its extracellular region, a transmembrane region, and two conserved tyrosine-based inhibitory signaling motif in its cytoplasmic region. Alternative splicing of CD33 RNA leads to a shorter isoform. CD33 is expressed on myeloid progenitors, granulocytes, monocytes, macrophages, dendritic cells, mast cells, subsets of activated T- and NK cells. It may mediate cell-to-cell adhesion and act as a receptor that inhibits the proliferation of normal and leukemic myeloid cells.
