Recombinant human WDR57 protein is a genetically engineered form of the WD repeat domain 57 (WDR57) protein, which belongs to the WD40 repeat protein family. WD40 proteins are characterized by conserved ~40-amino acid repeats (WD motifs) that fold into β-propeller structures, facilitating protein-protein or protein-nucleic acid interactions. WDR57. encoded by the WDR57 gene on chromosome 1p36.11. is implicated in diverse cellular processes, including RNA metabolism, genome stability, and cell cycle regulation. Studies suggest its role in stabilizing or assembling ribonucleoprotein complexes, potentially influencing mRNA processing or translation. Dysregulation of WDR57 has been linked to developmental disorders and cancer progression, though its exact molecular mechanisms remain under investigation.
The recombinant protein is typically expressed in *E. coli* or mammalian cell systems, enabling studies on its structure, interactome, and functional roles. It serves as a critical tool for *in vitro* assays, antibody production, and exploring pathological pathways. Research highlights its interaction with proteins like TUT1 (terminal uridylyl transferase 1), implicating it in post-transcriptional RNA modification. Biophysical characterization reveals its modular architecture, with WD40 domains acting as scaffolds for multiprotein complexes. Continued exploration of recombinant WDR57 may advance understanding of its contributions to cellular homeostasis and disease, offering potential therapeutic targets.
