The protein encoded by this gene belongs to the phosphatidylinositol 3,4,5-trisphosphate (PIP3)-dependent Rac exchanger (PREX) family, which are Dbl-type guanine-nucleotide exchange factors for Rac family small G proteins. Structural domains of this protein include the catalytic diffuse B-cell lymphoma homology and pleckstrin homology (DHPH) domain, two disheveled, EGL-10, and pleckstrin homology (DEP) domains, two PDZ domains, and a C-terminal inositol polyphosphate-4 phosphatase (IP4P) domain that is found in one of the isoforms. This protein facilitates the exchange of GDP for GTP on Rac1, allowing the GTP-bound Rac1 to activate downstream effectors. Studies also show that the pleckstrin homology domain of this protein interacts with the phosphatase and tensin homolog (PTEN) gene product to inhibit PTEN phosphatase activity, thus activating the phosphoinositide-3 kinase (PI3K) signaling pathway. Conversely, the PTEN gene product has also been shown to inhibit the GEF activity of this protein. This gene plays a role in insulin-signaling pathways, and either mutations or overexpression of this gene have been observed in some cancers.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eComparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).\u003c\/li\u003e \u003cli\u003eSubcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.\u003c\/li\u003e \u003cli\u003eIntegration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative\/positive controls for interpretation.\u003c\/li\u003e \u003cli\u003eELISA: researchers commonly compare relative signal levels across conditions and use appropriate negative\/positive controls for interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eInterpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands\/signals accordingly.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eEpitope context:\u003c\/strong\u003e binding can depend on protein conformation and sample processing; region information in the title\/immunogen can help anticipate what may be detected.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSpecies differences:\u003c\/strong\u003e predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControl concepts:\u003c\/strong\u003e include negative controls (no-primary\/isotype), and where possible genetic controls (KO\/KD) or independent antibodies to strengthen conclusions.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry Q70Z35 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/Q70Z35 - Gene search: DEPDC2 — NCBI Gene — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=DEPDC2 - Ensembl search: DEPDC2 — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=DEPDC2 - PubMed search: DEPDC2 antibody — PubMed — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=DEPDC2+antibody - Reactome search: DEPDC2 — Reactome — https:\/\/reactome.org\/content\/query?q=DEPDC2 --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml if reconstituted with 0.2ml sterile DI water \/ 100 ug","offer_id":53046460711277,"sku":"RQ8019","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_c1f7065c-31b8-4081-846e-7347def1e11d.jpg?v=1772000777","url":"https:\/\/www.ebiohippo.com\/products\/prex2-antibody-depdc2-bha17129579","provider":"BioHippo","version":"1.0","type":"link"}
