SMARCE1 Knockout Cell Line (HEK293)

The choice depends on whether you are studying SMARCE1's role in the BAF (SWI/SNF) chromatin remodeling complex or its emerging functions in cancer biology, particularly in meningioma and small cell carcinoma of the ovary. The Knockout line is appropriate for asking whether SMARCE1 is required for BAF complex assembly and chromatin remodeling activity. Overexpression is useful for studying SMARCE1's role as a context-dependent transcriptional co-regulator. For chromatin remodeling research, the EDITGENE SMARCE1 Knockout in HEK293 provides a mechanistic platform — HEK293 supports the high-quality ChIP and biochemical analyses needed for BAF complex characterization. SMARCE1 mutations cause familial meningioma (clear cell subtype) and SCCOHT — disease variant rescue enables genotype-function studies. Rescue with wild-type or HMG-domain-mutant SMARCE1 enables structure-function dissection.

Primary applications: • BAF complex composition: glycerol gradient or size-exclusion chromatography analysis of BAF complex integrity in the absence of SMARCE1. • ChIP-seq for BAF subunits: chromatin occupancy mapping of remaining BAF components following SMARCE1 loss to assess targeting defects. • Disease modeling: rescue with meningioma- or SCCOHT-associated SMARCE1 variants for genotype-function studies. • Synthetic lethality screening: combinatorial CRISPR screens to identify SMARCE1-loss vulnerabilities relevant to cancer therapy. EDITGENE recommends this model for researchers investigating BAF (SWI/SNF) complex biology, SMARCE1-related cancers, and chromatin remodeling mechanisms.

Yes. SMARCE1 rescue experiments require attention to BAF complex assembly: • Construct design: use a codon-modified SMARCE1 sequence with a small C-terminal tag (FLAG, HA). The N-terminal HMG-like domain mediates DNA binding and protein interactions — large N-terminal tags should be avoided. • HMG-domain-mutant rescue: HMG-box mutations affecting DNA binding distinguish DNA-engagement-dependent functions from scaffolding roles. • Disease mutation rescue: meningioma-associated (clear cell subtype) and SCCOHT-associated SMARCE1 variants enable genotype-function studies. • Functional readout: rescue should restore BAF complex composition (assessed by glycerol gradient) and chromatin occupancy of other BAF subunits. HEK293 transduces efficiently with lentivirus and supports the biochemical assays needed for BAF complex characterization.
