Expressed in spleen, prostate, testis, uterus, small intestine and skeletal muscle. Among hematopoietic cell lines, expressed exclusively in B-cells. Not expressed in most tumor cell lines.
Cytoplasm. Cell membrane. Cytoplasmic before PDGF stimulation. After PDGF stimulation, localized at the cell membrane and peripheral region.
