This protein is a family member of actin-related proteins (ARPs), which share significant amino acid sequence identity to conventional actins. Both actins and ARPs have an actin fold, which is an ATP-binding cleft, as a common feature. The ARPs are involved in diverse cellular processes, including vesicular transport, spindle orientation, nuclear migration and chromatin remodeling. This protein is a 53 kDa subunit of the BAF (BRG1/brm-associated factor) complex in mammals, which is functionally related to SWI/SNF complex in S. cerevisiae and Drosophila; the latter is thought to facilitate transcriptional activation of specific genes by antagonizing chromatin-mediated transcriptional repression. Together with beta-actin, it is required for maximal ATPase activity of BRG1, and for the association of the BAF complex with chromatin/matrix. It is required for maximal ATPase activity of SMARCA4/BRG1 and for association of the SMARCA4/BRG1 containing remodelling complex BAF with chromatin/nuclear matrix. It is a component of the NuA4 histone acetyltransferase (HAT) complex which is involved in transcriptional activation of select genes principally by acetylation of nucleosomal histone H4 and H2A. This modification may both alter nucleosome - DNA interactions and promote interaction of the modified histones with other proteins which positively regulate transcription. This complex may be required for the activation of transcriptional programs associated with oncogene and proto-oncogene mediated growth induction, tumor suppressor mediated growth arrest and replicative senescence, apoptosis, and DNA repair. NuA4 may also play a direct role in DNA repair when recruited to sites of DNA damage. -

Predicted band size: 47 kDaTotal extracts from two different clones of MCF7 (Human breast adenocarcinoma cell line) cells expressing a TAP tagged version of Tip60 were partially purified over IgG sepharose resin and eluted with TEV protease. Western blot was performed using a 1/1000 dilution of the BAF53A antibody.

Lane 2. TEV elution of Tip60-TAP clone #2
Lane 3. Total extract of Tip60-TAP clone #1
Lane 4. Total extract of Tip60-TAP clone #2NB: Tip60 is detected in the total extract due to the presence of Protein A in the TAP Tag (to which the primary and secondary abs bind). The TEV protease removes the Tag in lanes 1 and 2.

ChIP - Anti-BAF53A antibody - ChIP Grade (ab3882)This image is courtesy of Sylvain DaujatSonicated Chromatin prepared from untreated (UI) or 17beta-estradiol (E2) treated MCF7 cells was subjected to the ChIP procedure with ab3882 to BAF53A and the immunoprecipitated chromatin was analysed in the proximal region of the estrogen-responsive pS2 promoter (as shown above) and quantified by real-time PCR (values are nomalized over inputs). The primers are designed to follow the nucleosome E (including the Estrogen Responsive Element ERE). 8 µl of ab3882 and 2x106 cells were used in each ChIP experiment.
