 This induces Brahma-associated factor 60c (Baf60c), one of three Baf60 variants (a, b, and c) that are mutually exclusively assembled into the SWI/SNF chromatin remodelling complex.Blocking Nodal and BMP also induces lineage-specific transcription factors Gata4 and Tbx5, which interact with Baf60c.Collectively, these proteins redirect SWI/SNF to activate the cardiac program of gene expression.
