General annotation (Comments)

Function	Required for maximal ATPase activity of BRG1 and are also required with BRG1 for association of the complex with chromatin/matrix By similarity.
Subunit structure	Component of the BAF complex, which includes at least actin (ACTB), ARID1A, ARID1B/BAF250, SMARCA2, SMARCA4/BRG1, ACTL6A/BAF53, ACTL6B/BAF53B, SMARCE1/BAF57 SMARCC1/BAF155, SMARCC2/BAF170, SMARCB1/SNF5/INI1, and one or more of SMARCD1/BAF60A, SMARCD2/BAF60B, or SMARCD3/BAF60C.
Subcellular location	Nucleus.
Sequence similarities	Belongs to the actin family.
Sequence caution	The sequence AAC78795.1 differs from that shown. Reason: Erroneous gene model prediction.
