1、Measured by the ability of the immobilized protein to support the adhesion of human red blood cells. The ED50 for this effect is 1‑4 µg/mL. 2、Immobilized Recombinant Human CD33 Protein (rp143966) at 2.0 μg/mL can bind Gemtuzumab (anti-CD33) (Ab175859). The ED50 for this effect is 391.3 ng/mL.
Putative adhesion molecule of myelomonocytic-derived cells that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,6-linked sialic acid. The 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. Induces apoptosis in acute myeloid leukemia (in vitro).
Post-translational
Phosphorylation of Tyr-340 is involved in binding to PTPN6 and PTPN11. Phosphorylation of Tyr-358 is involved in binding to PTPN6.
