Revvity HTRF Total SMARCA-4 Detection Kit, 10,000 Assay Points

The SMARCA subgroup of genes belongs to the SWI/SNF family, involved in chromatin remodeling and DNA damage repair. SWI/SNF complexes regulate the genes involved in essential processes such as DNA replication, damage repair, and cell proliferation.

SMARCA4/BRG1 loss of function is frequently associated with cancer, and a synthetic lethal relationship between SMARCA4 and SMARCA2 /BRM is well established in SMARCA4-deficient cancers, where the inactivation of SMARCA2 leads to tumor cell death.

Among therapeutic strategies being investigated to fight cancers, targeted protein degradation is expected to overcome some limitations from conventional small molecules. So far, PROTAC molecules have been developed to induce selective degradation of SMARCA proteins. However, SMARCA2 and SMARCA4 share about 75% identity at the protein level, and so compounds are likely to target both proteins. Therefore, the selectivity of compounds targeting either SMARCA2 or SMARCA4 must be carefully investigated. In such investigations, the HTRF total SMARCA2 kit is a valuable companion assay for the HTRF total SMARCA4 kit, enabling reliable compound profiling.
