IHC staining of SMARCA4/BRG1 on formalin-fixed paraffin-embedded human colon tissue, following antigen retrieval using Sodium Citrate H.I.E.R. (Cat. No. 928502). Tissue sections were incubated without (panel A) and with (panel B and C) Purified anti-SMARCA4/ BRG1 (clone W22111B) overnight at 4°C followed by incubation with Alexa Fluor® 647 Goat anti-Rat IgG (Cat. No. 405416) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801). Panel B is overlay of DAPI and Alexa Fluor® 647 channel, and panel C is Alexa Fluor® 647 channel only. Images were captured using a 40X objective.

    Whole cell extracts (15 µg total protein) from indicated cell lines were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with Purified anti-SMARCA4/BRG1 (clone W22111B) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP Goat anti-Rat IgG (Cat. No. 405405). Direct-Blot™ HRP anti-GAPDH (Cat. No. 607903) was used as a loading control. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker.

Description

The transcription regulator SMARCA4/BRG1 is part of the SWI/SNF protein family and regulates chromatin structure in an ATP-dependent manner. It has helicase and ATPase activities which are required for chromatin topology remodeling. SMARCA4/BRG1 is important in transcriptional regulation of several genes involved in stress responses, neurogenesis, cell cycle, and differentiation. In this context, transcription of c-FOS in resting neurons is inhibited by recruitment of phospho RB1-HDAC complex by SMARCA4/BRG1. Alternatively, the CREST-BRG1 complex induces NR2B expression by binding to its promotor. In addition, SMARCA4/BRG1 regulates the expression of the tumorigenic protein CD44. Lastly, mutations in the SMARCA4 gene have been associated with rhabdoid tumor predisposition syndrome type 2.
