WDR18 (WD repeat domain 18) is a conserved eukaryotic protein belonging to the WD40-repeat family, characterized by tandem repeats of ~40-60 amino acids often terminating with tryptophan-aspartic acid (WD) motifs. These proteins typically form β-propeller structures that mediate diverse protein-protein interactions. WDR18 is ubiquitously expressed and localizes predominantly to the nucleolus, suggesting roles in ribosome biogenesis, though its precise molecular functions remain under investigation. It interacts with multiple partners, including the RNA polymerase I-associated factor PHAX and components of the B-WICH chromatin-remodeling complex, linking it to rRNA processing, chromatin dynamics, and transcriptional regulation.
Studies indicate WDR18 may participate in DNA damage repair pathways, cell cycle control, and stress responses. Depletion experiments in model organisms and cell lines have implicated it in maintaining genomic stability and mitotic fidelity. While not yet fully characterized, its conserved WD40 domains and nucleolar association hint at scaffolding roles in assembling macromolecular complexes. Dysregulation of WDR18 has been weakly associated with cancer progression and developmental disorders, though causal mechanisms are unclear.
Recombinant human WDR18 protein, often produced in E. coli or mammalian systems with affinity tags (e.g., GST, His-tag), enables functional studies, interaction mapping, and antibody development. Its modular structure and interaction versatility make it a target for exploring nucleolar processes and disease-related pathways. Further research is needed to elucidate its specific contributions to cellular homeostasis and pathology.
