"Data (including data from studies using knockout mice) suggest that Brg1 is phosphorylated by casein kinase 2 (Ck2; Ck2alpha1 and Ck2alpha-prime are catalytic subunits) in proliferating skeletal myoblasts; Brg1 is catalytic subunit of SWI/SNF chromatin-remodeling enzymes; Ck2-mediated phosphorylation of Brg1 appears to regulate myoblast proliferation. (Brg1 = Brahma-related gene 1 protein)"xsd:string
