**Background of Recombinant Human WDSUB1 Protein**
The WDSUB1 (WD Repeat Domain, UBA-like and SUB1-associated region) protein is a structurally complex molecule implicated in diverse cellular processes. Characterized by its WD40 repeats—a conserved domain facilitating protein-protein interactions—WDSUB1 is thought to regulate signaling pathways, transcriptional modulation, and chromatin remodeling. Its UBA-like domain may mediate ubiquitin-related processes, suggesting roles in protein degradation or DNA repair. Additionally, the SUB1-associated region hints at interactions with transcription factors like SUB1/PC4. potentially influencing RNA polymerase II activity.
Recombinant human WDSUB1 is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells) to enable functional studies. Purification typically involves affinity chromatography, yielding high-purity protein for *in vitro* assays. Research highlights its involvement in stress responses, cell cycle regulation, and tumorigenesis, with dysregulation linked to cancers and developmental disorders. Structural studies aim to map binding interfaces, while knockdown experiments explore its regulatory networks. As a multifaceted adaptor protein, WDSUB1 remains a focus for understanding cellular homeostasis and disease mechanisms.
