**Background of FUBP3 Recombinant Protein**
FUBP3 (Far Upstream Element-Binding Protein 3) is a member of the FUBP family of DNA/RNA-binding proteins, known for their roles in transcriptional and post-transcriptional regulation. It interacts with far upstream elements (FUEs) in gene promoters, notably regulating the expression of proto-oncogenes like *c-Myc*. While FUBP1. its well-studied homolog, is linked to cell proliferation and cancer, FUBP3 remains less characterized but shares structural features, including a central nucleic acid-binding domain and regulatory regions for protein interactions.
Recombinant FUBP3 protein is engineered using heterologous expression systems (e.g., *E. coli*, mammalian cells) to produce purified, functional protein for mechanistic studies. Its production enables exploration of FUBP3’s role in gene regulation, particularly in stress responses, apoptosis, and differentiation. Dysregulation of FUBP3 has been implicated in diseases such as neurodegeneration and cancer, making it a potential therapeutic or diagnostic target.
In research, recombinant FUBP3 aids in elucidating its DNA/RNA-binding specificity, interactions with transcriptional machinery, and modulation of splicing events. However, challenges like maintaining solubility and post-translational modifications in non-native systems may affect activity. Ongoing studies focus on resolving its precise molecular functions and disease associations, leveraging recombinant tools to bridge gaps in understanding its regulatory networks and therapeutic potential.
