Target information

CD33 is a transmembrane protein of the sialic acid-binding immunoglobulin (Siglec) family of lectins. It belongs to molecules containing the immunoreceptor tyrosine-based inhibitory motif (ITIMs) capable of recruiting protein tyrosine phosphatases SHP-1 and SHP-2 to signal assemblies, and these ITIMs are also used for ubiquitin-mediated elimination of the surface cell receptor. CD33 is expressed on cells of the myelomonocyte lineage, binds sialic acid residues in cell surface N- and O-glycans, and is a therapeutic target for acute myeloid leukemia.

Additionally, CD33 is found on granulocyte and macrophage precursors in the bone marrow, but not on pluripotent stem cells. CD33 is also expressed on, and is a useful marker for, peripheral monocytes. CD33 is useful in distinguishing myeloid leukemia cells from lymphoid or erythroid leukemias. Diseases associated with CD43 dysfunction include gallbladder lymphoma and extracutaneous mast cell tumor.
