The receptor, found on
pluripotent progenitor cells, induces
tyrosine phosphorylation within the cell and promotes proliferation and differentiation within the
hematopoietic cell lines. It can be found on
basophils and
pDCs as well as some
cDCs among peripheral blood mononuclear cells. CD123 is expressed across
acute myeloid leukemia (AML) subtypes, including leukemic
stem cells. ==Possible drug target==
