what is chromatin remodeling complex switchSWISNF

The chromatin remodeling complex switch/SWI/SNF is a protein complex that is involved in the regulation of gene expression by modifying the structure of chromatin. It is also known as the Brg/Brm-associated factor (BAF) complex. The SWI/SNF complex is composed of multiple subunits, including the ATPase subunits Brg1 or Brm, which use ATP hydrolysis to change the position and accessibility of nucleosomes on DNA. This allows transcription factors and other regulatory proteins to bind to DNA and activate or repress gene expression. The SWI/SNF complex is involved in a wide range of cellular processes, including development, differentiation, and tumorigenesis
