RSC30 Antibody

Research Applications of RSC30 Antibody

The antibody is widely used to investigate:

• Chromatin remodeling mechanisms: Identifies RSC30 localization at DNA double-strand breaks (DSBs) via chromatin immunoprecipitation (ChIP) .

• Protein interaction networks: Validates physical interactions with yKu80, Mre11, and Rsc1/2 in co-immunoprecipitation assays .

• Gene expression profiling: Correlates RSC30 loss with downregulation of cell wall integrity genes (CRH1, FKS1) and spindle checkpoint pathways .

DNA Repair and Chromatin Dynamics

• Non-homologous end joining (NHEJ):

  • rsc30Δ mutants exhibit a 2.4-fold reduction in CA insertions at DSB repair junctions and increased large deletions (>700 bp) .

  • Recruitment to DSBs depends on Mre11 and yKu70 .

• Nucleosome remodeling:

  • RSC30-containing RSC complexes show reduced nucleosome sliding activity compared to RSC2 isoforms .

Functional Redundancy and Genetic Interactions

• Suppression mechanisms: Overexpression of RSC3 rescues viability defects in rsc7Δ and rsc14Δ mutants .

• Phenotypic traits:

  • rsc30Δ strains are viable but osmosensitive .

  • Synthetic lethality occurs when combined with rsc7Δ or htl1Δ mutations .

Expression and Regulation

• Transcriptional impact:

  • RSC30 deletion downregulates 9% of yeast genes, including those involved in cell wall biogenesis (SLT2, CHS3) .

  • Upregulates stress-response pathways under DNA damage .

Future Directions

• Therapeutic potential: Targeting RSC30-interaction domains could modulate chromatin dynamics in fungal infections.

• High-resolution mapping: Advanced Cryo-EM studies are needed to resolve RSC30’s role in RSC-nucleosome interactions .
