  5. Chemotaxis mediated by chemokine receptors, such as cxcr4, play a key role in lymphocyte homing and hematopoiesis as well as in breast cancer metastasis. we have previously demonstrated that ? - arrestin2 functions to attenuate cxcr4 - meidated g protein activation and to enhance cxcr4 internalization. here we further show that expression of ( - arrestin2 in both hela and hek293 cells significantly enhanced the chemotactic efficacy of stromal - cell derived factor 1 ( ( sdf - 1 ( ), the specific agonist of cxcr4

    - arrestin2是趨化因子受體的一種重要的調節蛋白，本研究工作發現在hek - 293或hela細胞中升高- arrestin2的表達水平會顯著增強cxcr4介導的趨化作用，反之當- arrestin2的表達被它的反義核苷酸或rnai所抑制， cxcr4介導的趨化作用則被明顯抑制。
