smarcb1 protein


Summary: A component of the SWI-SNF CHROMATIN REMODELING complex that functions as a PROTEIN PHOSPHATASE 1 regulator and to stabilize CHROMATIN at PROMOTER REGIONS. It is important for regulating CELL PROLIFERATION and CELL DIFFERENTIATION. Mutations in the SMARCB1 gene are associated with malignant RHABDOID TUMORS.
