RSC-type complex
Definition
Target type: cellularcomponent
A SWI/SNF-type complex that contains a bromodomain containing-protein, such as yeast Rsc1 or Rsc4 or mammalian PB1/BAF180. The RSC complex is generally recruited to RNA polymerase III promoters and is specifically recruited to RNA polymerase II promoters by transcriptional activators and repressors; it is also involved in non-homologous end joining.

The RSC-type complex is a large, multi-protein complex that plays a critical role in chromatin remodeling. It is composed of several subunits, each with its own unique function. The core of the RSC complex is formed by the ATPase subunit SNF2h, also known as BRG1. SNF2h is a member of the SWI/SNF family of ATP-dependent chromatin remodelers and is responsible for providing the energy required for chromatin remodeling. The SNF2h subunit interacts with a variety of other subunits, including the SWI/SNF-associated proteins (SWI/SNF-AP) such as SNF5 and BAF57, which contribute to the overall stability of the complex. In addition to these core subunits, the RSC complex also contains a number of other subunits that are involved in specific functions. For example, the RSC complex includes subunits that interact with histone modifications, allowing it to target specific regions of the genome. These subunits can also interact with other proteins, such as transcription factors, to regulate gene expression. The RSC complex is a highly dynamic structure that can be assembled and disassembled in response to various cellular signals. This flexibility allows the RSC complex to adapt to different cellular needs and regulate a wide range of cellular processes, including DNA replication, transcription, and repair.'
