摘要:

HSPC300/hHBRK1 蛋白作为BRK1 的人类同源蛋白,参与细胞运动和物质运输.肌球蛋白Ⅵ是肌球蛋白家族的成员.HSPC300/hHBRK1和肌球蛋白Ⅵ共同定位于细胞的胞浆,hHBRK1 可能通过与肌球蛋白Ⅵ相互作用,参与细胞内的物质运输.从结构角度出发,通过计算机模拟蛋白质间相互作用,预测二者作用区域,找出相关残基PHE43,LYS105,THR676和LEU40,即可能成为相互作用位点的重要残基,为进一步实验研究提供了重要信息.

Abstract:

HSPC300/hHBRK1 protein involved in cell movement and material transport is a kind of human homologous proteins. Myosin Ⅵ protein is a member of the myosin family. It is possible that HSPC300/hHBRK1 protein andmyosin Ⅵ protein react for the reason that they are present in the cytoplasm of cells and they are both involved inintracellular transport of the material. To lay a foundation for further experiments, we predict the area of interactionunder the structural point by computer simulation of proteinprotein interactions, and find the related residues that may become the sites of amino acid interaction: PHE43, LYS105, THR676 and LEU40.

Key words: HSPC300/hHBRK1; myosin Ⅵ; structure prediction; docking
