**Background of DCAF7 Recombinant Protein**
DCAF7 (DDB1- and CUL4-associated factor 7), also known as WDR68 or HAN11. is a scaffold protein involved in diverse cellular processes, including signal transduction, transcriptional regulation, and cell cycle control. It belongs to the WD40-repeat protein family, characterized by conserved β-propeller domains that mediate protein-protein interactions. DCAF7 acts as an adaptor component of the CRL4 (Cullin-RING ubiquitin ligase 4) complex, which participates in ubiquitination and proteasomal degradation of target proteins.
A key functional role of DCAF7 lies in its interaction with the serine/threonine kinase DYRK1A (dual-specificity tyrosine-regulated kinase 1A). This interaction facilitates the assembly of a DYRK1A-DCAF7 complex, which regulates downstream pathways such as the RAS/MAPK and Wnt/β-catenin signaling cascades. These pathways are critical for cell proliferation, differentiation, and embryonic development. Dysregulation of DCAF7 has been implicated in developmental disorders, including autism spectrum disorders, and cancer, where it may act as a tumor suppressor or oncogenic cofactor depending on cellular context.
Recombinant DCAF7 protein is engineered for in vitro studies to elucidate its structural and functional roles. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), it retains native folding and interaction capabilities. Researchers utilize this tool to investigate DCAF7’s binding partners, its role in ubiquitination cascades, and its involvement in disease mechanisms. Additionally, recombinant DCAF7 aids in screening for therapeutic agents targeting DYRK1A-associated pathologies or CRL4-dependent processes. Its study continues to shed light on molecular networks governing cellular homeostasis and disease, making it a focal point in both basic and translational research.
