| Popis: | Many studies have now established that the SWI/SNF chromatin remodelling complexes are involved in activation and repression of a variety of genes. In mammalian cells, these complexes contain the BRM and BRG1 helicase-like proteins that are thought to be responsible for nucleosome remodelling. The proto-oncoprotein SYT, involved in the unique translocation t(X;18) found in synovial sarcoma, is known to interact with human BRM (hBRM), thus providing a link between chromatin remodelling factors and human cancer. In this work, we address how SYT interacts with hBRM and BRG1. We demonstrate that the conserved N-terminal SNH domain of SYT, which is also present in the oncoproteins SYT-SSX, binds to both hBRM and BRG1. We have also found that in vivo the C-terminus transactivation QPGY region of SYT can interact with itself. This results in an amplified interaction with hBRM and highlights a possible regulatory function of this domain in cells. |
