This product corresponds to the Mycobacterium tuberculosis (strain CDC 1551 \/ Oshkosh) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt\/NCBI) and the recent literature for the specific organism and isoform.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eUsing recombinant proteins to enable quantitative binding measurements and reagent benchmarking.\u003c\/li\u003e \u003cli\u003eStudying domain- and isoform-specific effects in pathway models and interaction networks.\u003c\/li\u003e \u003cli\u003eDeveloping robust, reproducible assays that connect molecular readouts to cellular phenotypes.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e The only predicted protein phosphatase in M.tuberculosis, it dephosphorylates at least 5 protein kinases (PknA, PknB, PknD, PknE and PknF) and the penicillin-binding protein PBPA.\u003c\/p\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eEnzyme activity assays and kinetics measurements with defined substrates\/cofactors.\u003c\/li\u003e \u003cli\u003eInhibitor, activator, or substrate screening in biochemical assay formats.\u003c\/li\u003e \u003cli\u003eStructure–function analysis to interpret how sequence changes impact catalytic performance.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn quantitative assay development, changes in binding or activity readouts are typically interpreted relative to appropriate negative\/positive controls and, where possible, orthogonal assay formats that support the same conclusion.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eRecombinant constructs may represent a defined region (domain) rather than the full-length protein; interpret results in the context of the expressed region.\u003c\/li\u003e \u003cli\u003eTag or fusion elements can aid purification and detection but may influence binding surfaces or oligomerization; consider tag controls when relevant.\u003c\/li\u003e \u003cli\u003eSpecies and isoform differences can affect interaction partners and post-translational modifications; align experimental controls to the intended biological context.\u003c\/li\u003e \u003cli\u003eE. coli expression can limit eukaryotic post-translational modifications; for modification-dependent biology, interpret results accordingly.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for P9WHW4 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P9WHW4\/entry - NCBI Gene search (pstP) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=pstP - PubMed search (pstP) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=pstP - RCSB PDB search (pstP) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=pstP - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065256698221,"sku":"CSB-EP301778GKB2a0-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065358934381,"sku":"CSB-EP301778GKB2a0-100UG","price":729.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065358967149,"sku":"CSB-EP301778GKB2a0-20UG","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP301778GKB2a0-SDS.jpg?v=1772476365","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-mycobacterium-tuberculosis-pp2c-family-ser-thr-phosphatase-pstp-partial-bhp10508523","provider":"BioHippo","version":"1.0","type":"link"}
