Is SWI SNF a coactivator?
The core component of the mammalian SWI/SNF complex SMARCD3/BAF60c is a coactivator for the nuclear retinoic acid receptor. Mol Cell Endocrinol. 2007 May 30;270(1-2):23-32.
What does BAF complex do?
Mechanistically, a BAF complex remodels chromatin using its ATPase core subunits to hydrolyze ATP and hence generate energy for nucleosomal unwrapping, mobilization, ejection, or histone dimer exchange (Cairns, 1998; Phelan et al., 1999; Whitehouse et al., 1999; Saha et al., 2002; Gutiérrez et al., 2007; Tang et al..

What is the BAF protein?
Abstract. Barrier-to-autointegration factor (BAF) is an essential protein that is highly conserved in metazoan evolution. BAF binds directly to double-stranded DNA, nuclear LEM-domain proteins, lamin A and transcription activators. BAF is also a host cell component of retroviral pre-integration complexes.
What is the BAF complex?
Abstract. The ATP-dependent chromatin remodelling complex BAF (= mammalian SWI/SNF complex) is crucial for the regulation of gene expression and differentiation. In the course of evolution from yeast to mammals, the BAF complex evolved an immense complexity with a high number of subunits encoded by gene families.
Is the TATA box found in all eukaryotic promoters?
Even though the TATA box is present in many eukaryotic promoters, is important to note that is not contained in the majority of promoters. One study found less than 30% of 1031 potential promoter regions contain a putative TATA box motif in humans.
Is the SWI / SNF complex a tumor suppressor?
The mammalian SWI/SNF (mSWI/SNF) complex functions as a tumor suppressor in many human malignant cancers. Early studies identified that SWI/SNF subunits were frequently absent in cancer cell lines.
Which is the negative regulator of SWI / SNF?
The protein domain, SWIB/MDM2, short for SWI/SNF complex B/MDM2 is an important domain. This protein domain has been found in both SWI/SNF complex B and in the negative regulator of the p53 tumor suppressor MDM2.
Is the SWIB complex homologous to the SNF complex?
The protein domain, SWIB/MDM2, short for SWI/SNF complex B/MDM2 is an important domain. This protein domain has been found in both SWI/SNF complex B and in the negative regulator of the p53 tumor suppressor MDM2. It has been shown that MDM2 is homologous to the SWIB complex.
How does the SWI / SNF subfamily promote gene expression?
Due to the actions performed by the SWI/SNF subfamily, they are referred to as “access remodellers” and promote gene expression by exposing binding sites so that transcription factors can bind more easily. Two mechanisms for nucleosome remodeling by SWI/SNF have been proposed.
