As we know, SWI/SNF is a global, untargeted chromatin remodeler which influence transcription, it perform gene-specific regulation by interacting with some selective activators. On the other hand, no known DNA-binding domain is found in BEX1. So we come to a conclusion that BEX1 may mediate activators interact with hSNF5, and this result in the transcription of specific sets of genes that control the cell cycle.
由于BEX1本身并未发现能与DNA直接结合,而hSNF5所在的染色质重塑复合体单独存在时作用没有特异性,我们推测,BEX1可能作为接头分子,介导了其它蛋白与hSNF5的作用,导致控制细胞周期相关基因的转录激活或抑制。

Determined by the specific geological background of Longhetun, the characteristics of the soil resources show abundant calcium and leaning to alkaline. Monomial indexes to evaluate the revisal coefficient of soil adapted to karst mountains areas were screened out combined with the function of karst dynamics system and analysis of characters of each factor about fertility in soil. Predigestion model to soil revisal coefficient monomial assessment was established by successful importation of the content of nutrition elements in plant body, latent efficient elements in soil and available thickness of soil in the cranny of epikarst according to the characters that three carriers of soil, soil water and karst water supply nutrition to plants and two layers of foundation consist of surface soil and soil in epikarst cranny, and several types of soil revisal coefficient and weather-soil productive potentiality were calculated, the results show that the soil revisal coefficient was even more practical after modification than before, which make up of innovation of this study.
