Encoded by the STAMBP gene on chromosome 2p13.1, this enzyme is a member of the JAMM (JAB1\/MPN\/Mov34 metalloenzyme) family of zinc-dependent deubiquitinases that cleave ubiquitin chains from endosomal cargo proteins. STAMBP plays a critical role in maintaining receptor turnover and preventing abnormal accumulation of ubiquitinated proteins within endosomes.\u003cbr\u003e\u003cbr\u003eStructurally, STAMBP is a 424-amino-acid cytoplasmic protein of approximately 49 kilodaltons containing a JAMM motif responsible for zinc ion coordination and catalytic activity, as well as SH3-binding regions that enable interaction with signal transducing adaptor molecules (STAM1 and STAM2). It localizes to early endosomes and participates in the endosomal sorting complex required for transport (ESCRT) machinery, modulating trafficking of growth factor receptors such as EGFR and cytokine receptors after ligand binding.\u003cbr\u003e\u003cbr\u003eThe STAMBP antibody is widely used in cell signaling, membrane trafficking, and neurodevelopmental research to study ubiquitin processing, receptor regulation, and lysosomal degradation pathways. Western blot analysis detects a 49 kilodalton band corresponding to STAMBP, while immunofluorescence reveals punctate endosomal staining. This antibody enables precise detection of endosomal deubiquitinating enzyme activity and ESCRT complex assembly.\u003cbr\u003e\u003cbr\u003eFunctionally, STAMBP removes Lys63-linked ubiquitin chains from endosomal cargo proteins, facilitating recycling or degradation decisions within the endolysosomal pathway. Its activity prevents overactivation of growth factor signaling and supports normal receptor turnover. Mutations in STAMBP cause microcephaly-capillary malformation syndrome (MIC-CAP), a rare congenital disorder characterized by neurodevelopmental delay, seizures, and vascular malformations resulting from defective ubiquitin recycling. Altered STAMBP expression also contributes to tumor progression and immune dysregulation through prolonged receptor signaling. The STAMBP antibody provides a powerful tool for characterizing ubiquitin-dependent trafficking, growth factor regulation, and endosomal sorting mechanisms.\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\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=STAMBP - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=STAMBP - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=STAMBP - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/STAMBP - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=STAMBP+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":53047305601389,"sku":"FY12890","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_cd1f8a29-0965-4284-a076-2e6320343d75.jpg?v=1782237055","url":"https:\/\/www.ebiohippo.com\/products\/stambp-antibody-stam-binding-protein-bha17135792","provider":"BioHippo","version":"1.0","type":"link"}
