白细胞介素3(IL-3)是一种造血生长因子,其支持早期造血谱系祖细胞的增殖和分化。通过使用生长因子依赖性细胞系,IL-3已显示诱导几种含磷酸酪氨酸的蛋白质的出现,包括140-kDa细胞表面磷蛋白。在这里,我们证明,140 kDa的磷蛋白结合IL-3,并形成一个稳定的复合物,表观分子量为170 kDa。140-kDa磷蛋白到先前描述的65-kDa IL-3结合蛋白的可能关系进行了讨论。
Interleukin 3 (IL-3) is a hematopoietic growth factor that supports the proliferation and differentiation of early hematopoietic-lineage progenitors. By using growth factor-dependent cell lines, IL-3 has been shown to induce the appearance of several phosphotyrosine-containing proteins, including a 140-kDa cell surface phosphoprotein. Here we demonstrate that the 140-kDa phosphoprotein binds IL-3 and forms a stable complex with an apparent molecular mass of 170 kDa. The possible relationship of the 140-kDa phosphoprotein to the previously described 65-kDa IL-3-binding protein is discussed.
