According to the previous results, BNIPL-2 could interact with Cdc42GAP and suppress the GAP activity of Cdc42GAP toward Cdc42. BNIPL-2 also had a BCH domain (BNIP-2 and Cdc42GAP homology), which could induce short and long pseudopodia, and subsequently was needed to trigger cell migration. So we presume BNIPL-2 could be involved in cell migration and cancer metastasis.

前期实验发现，BNIPL-2可以和Cdc42GAP发生相互作用，并且抑制Cdc42GAP的活性；而且BNIPL-2中有一个重要的结构域：BCH domain，它可以诱导细胞伪足的产生，从而参与调节细胞的运动，提示了BNIPL-2可能参与细胞的运动和肿瘤转移。

The special tribo-electdc tester with high sliding speed and electric current was developed,which mail working parameters are, current density up to 2.5 A/mm~2, the sliding speed 100 m/s,the load over 500 N (3.2 MPa) and the pulsant strike pressure within 20 N. This testersuccessfully simulates the tribological and electric properties of strip materials. 2, By using the above tester, study on tdbological properties and carrying currentperformances of copper-base powder metallurgy material and metal impregnation carbonmaterial are carded out.
