PSE7 and SOJB had the similar binding proteins in tobacco, suggesting that they may share some similar biological functions. The ubiquitin-conjugating protein and peptidase involved in protein degradation were found binding with SOJB but not PSE7. Both SOJB and PSE7 could bind with transmembrane transport protein, SOJB bound with copper transporter protein, and PSE7 bound with water channel protein. The results suggested that the target of SOJB and PSE7 may be located in cytoplast.

PSE7和SOJB在烟草中存在几个相似的结合蛋白，表明二者具有共享的生物学功能；SOJB能与肽酶和泛素结合蛋白（与蛋白质降解有密切关系）互作，而PSE7没有筛选到类似蛋白；SOJB和PSE7均能与跨膜运输蛋白结合，PSE7与水通道蛋白结合，SOJB与铜离子转运蛋白结合，表明二者在胞质内均存在作用靶标。
