简介
The PC4/SUB1 protein acts as a multifunctional coactivator that cooperates with TAF to promote functional interactions between upstream activators and the general transcription machinery. Its role extends to the potential stability of multiprotein transcription complexes. PC4/SUB1 Protein, Human (His) is the recombinant human-derived PC4/SUB1 protein, expressed by E. coli , with N-His labeled tag.

Protein Description
The PC4/SUB1 protein, initially identified as a factor involved in the regulation of gene expression in yeast, has garnered significant attention in recent years due to its multifaceted roles in various biological processes. This protein is known to participate in DNA repair, transcription regulation, and cellular responses to stress, making it a crucial player in maintaining genomic stability and proper cellular function. Studies have revealed that PC4/SUB1 can interact with a variety of proteins and DNA elements, influencing the transcriptional machinery and facilitating the recruitment of RNA polymerase II to specific gene promoters. Furthermore, its involvement in the cellular response to environmental stimuli highlights its potential relevance in cancer biology and other diseases where gene regulation is disrupted. The characterization of PC4/SUB1 as a nuclear protein involved in the assembly of transcription complexes has opened new avenues for understanding how eukaryotic cells regulate gene expression under diverse conditions. Given its pivotal role, ongoing research seeks to elucidate the molecular mechanisms governing PC4/SUB1 function and its implications in cellular processes, which could lead to novel therapeutic strategies targeting related pathways in human diseases.
