WDR4 forms a complex with METTL1 to catalyze the N7-methylguanosine modification of tRNAs, a modification required for translational fidelity and RNA stability. The WDR4 antibody is widely used in molecular biology and RNA research to study RNA methylation, protein translation, and gene expression regulation.\u003cbr\u003e\u003cbr\u003eWDR4 is encoded by the WDR4 gene located on human chromosome 21q22.3. The protein is approximately 412 amino acids long and contains several WD40 repeats that mediate protein-protein interactions, forming a beta-propeller structure typical of the WD repeat family. WDR4 localizes to the nucleus and cytoplasm, where it partners with METTL1 to catalyze methylation of specific tRNA guanine residues, ensuring proper translation initiation and elongation.\u003cbr\u003e\u003cbr\u003eThe WDR4 antibody detects a 46 kilodalton protein by western blot and demonstrates nuclear and cytoplasmic staining patterns under immunofluorescence. Through its interaction with METTL1, WDR4 stabilizes the tRNA methyltransferase complex and regulates global protein synthesis. Loss of WDR4 leads to reduced tRNA methylation, impaired translation, and increased sensitivity to stress.\u003cbr\u003e\u003cbr\u003eMutations in WDR4 cause a spectrum of developmental and neurological disorders, including microcephaly and intellectual disability. These defects arise from disrupted tRNA modification, which affects the translation of growth-related and neuronal genes. In cancer, overexpression of WDR4 enhances translation of oncogenic proteins and promotes tumor progression through metabolic reprogramming.\u003cbr\u003e\u003cbr\u003eBecause of its key role in RNA modification and translation regulation, WDR4 serves as an essential model for understanding epitranscriptomic control of gene expression.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence:\u003c\/strong\u003e visualize subcellular distribution and cell-to-cell heterogeneity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Monoclonal antibodies provide a defined epitope recognition profile that can support consistent comparisons across experiments.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=WDR4 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=WDR4 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=WDR4 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/WDR4 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=WDR4+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Rabbit IgG in phosphate buffered saline, pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol, 0.4-0.5mg\/ml BSA \/ 100 ul","offer_id":53047293378925,"sku":"FY12587","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_a98884a4-5e55-43b3-8ba0-18b3e150bfea.jpg?v=1772019319","url":"https:\/\/www.ebiohippo.com\/products\/wdr4-antibody-wd-repeat-domain-4-bha17135490","provider":"BioHippo","version":"1.0","type":"link"}
