BAF57/SMARCE1 directly binds to the androgen receptor (AR) and is recruited to endogenous AR target genes upon ligand activation; loss of BAF57 severely compromises AR-dependent transactivation and AR-dependent proliferation in prostatic adenocarcinoma cells, and this action depends on SWI/SNF ATPase function. |

SMARCE1 plays a structural role in selectively stabilizing the canonical BAF (cBAF) complex core-ATPase module interaction; loss of SMARCE1 in clear cell meningioma causes cBAF complexes to fail to stabilize on chromatin, reduces enhancer accessibility, and increases formation of ncBAF complexes; SMARCE1-deficient cells are hypersensitive to ncBAF inhibition. |
