The UniProt recommended name is Presenilins-associated rhomboid-like protein (PARL). This serine protease participates in the regulated intramembrane proteolysis of substrates that control mitochondrial morphology and quality control.\u003cbr\u003e\u003cbr\u003eFunctionally, PARL antibody identifies a 379-amino-acid protein localized to the inner mitochondrial membrane. PARL cleaves and activates key mitochondrial substrates such as PINK1 and PGAM5, initiating mitophagy and apoptosis signaling pathways. Through these actions, PARL maintains mitochondrial homeostasis and protects cells from oxidative stress. It also participates in remodeling the inner membrane during stress conditions, influencing cristae organization and mitochondrial fission-fusion balance.\u003cbr\u003e\u003cbr\u003eThe PARL gene is located on chromosome 3q27.1 and is expressed in metabolically active tissues including brain, heart, and skeletal muscle. Expression levels fluctuate with energy demand and stress, with upregulation observed during mitochondrial biogenesis and differentiation. PARL is evolutionarily conserved across eukaryotes, emphasizing its fundamental role in organelle maintenance.\u003cbr\u003e\u003cbr\u003ePathologically, mutations in PARL have been associated with mitochondrial dysfunction, Parkinson's disease, and metabolic disorders. Impaired PARL activity disrupts PINK1 processing, leading to defective mitophagy and accumulation of damaged mitochondria. In contrast, overexpression may alter apoptotic sensitivity by influencing cytochrome c release. Research using PARL antibody supports studies in mitochondrial biology, apoptosis regulation, and neurodegenerative disease.\u003cbr\u003e\u003cbr\u003ePARL antibody can be validated for western blotting, immunofluorescence, and immunohistochemistry to detect mitochondrial proteases. \u003cbr\u003e\u003cbr\u003eStructurally, Presenilins-associated rhomboid-like protein contains seven transmembrane domains forming a proteolytic chamber within the inner mitochondrial membrane. Its catalytic serine and histidine residues form the rhomboid protease active site. The protein's C-terminal region undergoes regulated processing, modulating its activity in stress conditions. This antibody enables investigation of PARL's role in mitochondrial proteostasis and apoptosis signaling.\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\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 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=PARL - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=PARL - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=PARL - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/PARL - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=PARL+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":53047320674669,"sku":"FY13274","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_6d3437d4-197a-43a2-a23d-3998138775bb.jpg?v=1782237093","url":"https:\/\/www.ebiohippo.com\/products\/parl-antibody-presenilins-associated-rhomboid-like-protein-bha17136176","provider":"BioHippo","version":"1.0","type":"link"}
