transcription factor

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus,nucleoplasm
	intracellular,nucleus,chromatin/chromosome

basic FUNCTION	involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology)
	may stimulate the ATPase activity of the catalytic subunit of the complex
	has a scaffold function in stabilizing the SWI/SNF-like BAF complex by interacting directly with the core subunits SMARCA4, SMARCB1, and SMARCD1
	is potentially required for angiogenesis and visceral endoderm development in the yolk sac
	novel function in tumor suppression, providing insights into genetic pathways dictating tumor suppression by the SWI/SNF complex
	SMARCC2, SMARCC1 play essential roles in specification, olfactory neural stem cells (oNSCs) proliferation and olfactory receptor neurons (ORNs) maturation of developing olfactory epithelium
	SMARCC1 SWIRM is a modular domain involved in SMARCB1 interaction, which is functionally distinct from other characterized SWIRM domains that possess DNA binding activity

CELLULAR PROCESS	nucleotide, chromatin organization, remodeling
	nucleotide, transcription, regulation

PHYSIOLOGICAL PROCESS

text	actin-dependent regulator of chromatin structure

PATHWAY

metabolism

signaling

a component	component of five multiprotein chromatin-remodeling complexes
	phosphorylated on undefined residues at the G2/M transition by ERK1 and other kinases
	core component of SWI/SNF complex

INTERACTION

DNA

binding

RNA

small molecule

protein	interacts with SMARCA4 through its highly conserved SANT domain
	function as a tumor suppressor by modulating CDKN1A expression
	CHFR interacts with SMARCA4, SMARCB1, and SMARCD1 of the SWI/SNF-like BAF complex and ubiquitinates them to target for degradation through a proteasome-mediated pathway, and SMARCC1 stabilizes these components by blocking their interaction with CHFR
	interacts with SMARCB1 and SMARCD1 through its conserved SWIRM domain
	stabilizes SMARCD1 by inhibiting the ubiquitination of SMARCD1, which is induced by CHFR
	RBM15, a subunit of the m6A methyltransferase complex, interacts with SMARCC1 mRNA and mediates BAF155 mRNA degradation through the mRNA methylation machinery
