The UniProt recommended name is PDZ domain-containing 1 (PDZK1). This adaptor protein interacts with various membrane-associated proteins, including ion channels, transporters, and signaling receptors, to regulate their surface expression and stability.\u003cbr\u003e\u003cbr\u003eFunctionally, PDZK1 antibody identifies a 519-amino-acid cytoplasmic protein containing four PDZ domains that mediate multiprotein complex formation at the apical membrane. PDZK1 anchors transporters such as the sodium-hydrogen exchanger NHE3 and the scavenger receptor SR-BI, facilitating ion exchange and lipid uptake. It coordinates interactions between membrane proteins and signaling molecules that maintain epithelial polarity and transport efficiency.\u003cbr\u003e\u003cbr\u003eThe PDZK1 gene is located on chromosome 1q21.1 and is highly expressed in kidney, liver, and intestine. In hepatocytes, PDZK1 regulates cholesterol homeostasis through its interaction with SR-BI, while in renal and intestinal epithelia it modulates absorption and reabsorption processes. PDZK1's scaffolding role ensures efficient communication between transporters and cytoskeletal components.\u003cbr\u003e\u003cbr\u003ePathologically, dysregulated PDZK1 expression is linked to disorders of lipid metabolism, hypertension, and cancer. Reduced PDZK1 can impair high-density lipoprotein (HDL) uptake and disrupt cholesterol transport. Overexpression has been associated with tumor progression through altered signaling dynamics. Research using PDZK1 antibody enhances understanding of epithelial transport regulation and metabolic signaling.\u003cbr\u003e\u003cbr\u003ePDZK1 antibody is suitable for western blotting, immunofluorescence, and immunohistochemistry to detect PDZK1 in epithelial tissues and cultured cells. \u003cbr\u003e\u003cbr\u003eStructurally, PDZK1 features four PDZ domains arranged to allow simultaneous binding of multiple partners, forming scaffolded microdomains at the plasma membrane. This antibody enables analysis of PDZK1-mediated protein complexes that maintain cellular polarity and metabolic balance.\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\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\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\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 Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=PDZK1 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=PDZK1 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=PDZK1 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/PDZK1 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=PDZK1+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047311925613,"sku":"FY13097","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_4330f280-1ec1-4d74-bb49-4b49080b4faf.jpg?v=1782237100","url":"https:\/\/www.ebiohippo.com\/products\/pdzk1-antibody-pdz-domain-containing-1-nherf3-bha17135999","provider":"BioHippo","version":"1.0","type":"link"}
