Blocking and diluting buffer and concentration : Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS. Lysates at 20 µg per lane. The samples were run on a Bis-Tris gel. Performed under reducing conditions. False colour image of Western blot : Anti-mSin3A antibody (ab307197) staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody 6C5 (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab307197 was shown to bind specifically to mSin3A. A band was observed at 170 kDa in wild-type HAP1 cell lysates with no signal observed at this size in mSin3A knockout cell line. To generate this image, wild-type and mSin3A knockout HAP1 cell lysates were analyzed. First, samples were run on an SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in in Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

Supplementary information

MSin3A also known as Sin3A is a transcriptional corepressor that plays an important role in regulating gene expression. It weighs approximately 155 kDa. You can find mSin3A expressed in various tissues throughout the body. This protein does not bind DNA directly but associates with DNA-binding proteins to exert its effects. mSin3A functions mechanically by interacting with histone deacetylases (HDACs) leading to the remodeling of chromatin and repression of gene transcription.
Biological function summary

MSin3A acts to regulate gene silencing and is a component of the mSin3A/HDAC complex. This complex is involved in the control of cell cycle progression differentiation and apoptosis. In cellular processes mSin3A serves as a scaffold binding various proteins to create a platform for gene regulatory functions. Its role in recruiting HDACs to specific genomic locations aids in transcriptional repression affecting many biological processes.

Pathways

MSin3A plays significant roles in the Notch and p53 signaling pathways. These pathways are essential in controlling cell fate decisions and responses to stress. mSin3A partners with HDAC1 and HDAC2 within these pathways facilitating the deacetylation and repression of target genes. In the Notch signaling pathway mSin3A interacts with repressors like CSL while in the p53 pathway it influences p53-dependent transcriptional outcomes by modifying the chromatin state.

MSin3A shows connection to cancer and neurodegenerative diseases. In cancer mSin3A affects tumor suppression through its interaction with p53 playing a role in cell cycle arrest and apoptosis. In neurodegenerative diseases mSin3A deregulation may disrupt chromatin architecture impairing neuronal function. By targeting mSin3A and associated proteins like HDAC1 researchers explore potential therapeutic avenues for these diseases.

Target data

Acts as a transcriptional repressor. Corepressor for REST. Interacts with MXI1 to repress MYC responsive genes and antagonize MYC oncogenic activities. Also interacts with MXD1-MAX heterodimers to repress transcription by tethering SIN3A to DNA. Acts cooperatively with OGT to repress transcription in parallel with histone deacetylation. Involved in the control of the circadian rhythms. Required for the transcriptional repression of circadian target genes, such as PER1, mediated by the large PER complex through histone deacetylation. Cooperates with FOXK1 to regulate cell cycle progression probably by repressing cell cycle inhibitor genes expression (By similarity). Required for cortical neuron differentiation and callosal axon elongation (By similarity).
