**Background of CRSP3 Recombinant Protein**
CRSP3 (Co-Repressor of Sp1 Protein 3) is a subunit of the CRSP (Co-Repressor of Sp1) complex, also known as the Mediator complex, which plays a pivotal role in regulating RNA polymerase II-mediated transcription. As part of this evolutionarily conserved multi-protein assembly, CRSP3 facilitates communication between transcription factors and the basal transcriptional machinery, enabling precise control of gene expression. The Mediator complex is essential for diverse cellular processes, including cell differentiation, development, and stress responses.
Recombinant CRSP3 protein is produced through genetic engineering, typically by expressing the CRSP3 gene in bacterial or mammalian systems, followed by purification using affinity tags. This engineered protein retains functional domains critical for interactions with other Mediator subunits, transcription factors (e.g., Sp1), and chromatin-modifying enzymes. Its recombinant form allows researchers to study CRSP3's structural and mechanistic roles in vitro, such as its involvement in enhancer-promoter looping, transcriptional initiation, or epigenetic regulation.
Studies leveraging CRSP3 recombinant protein have shed light on its dysregulation in diseases, including cancers and metabolic disorders, where aberrant transcriptional programs drive pathogenesis. Additionally, it serves as a tool for screening small-molecule inhibitors targeting Mediator-dependent oncogenic pathways. By enabling detailed biochemical and structural analyses, recombinant CRSP3 contributes to understanding fundamental gene regulation mechanisms and developing therapeutic strategies for transcription-related diseases.
In summary, CRSP3 recombinant protein is a vital resource for dissecting the Mediator complex's role in transcription and its implications in health and disease.
