In contrast to PARP1 and PARP2, it is not able to mediate poly-ADP-ribosylation (PubMed:25043379). Has been shown to catalyze the mono-ADP-ribosylation of STAT1 at 'Glu-657' and 'Glu-705', thus decreasing STAT1 phosphorylation which negatively regulates pro-inflammatory cytokine production in macrophages in response to IFNG stimulation (PubMed:27796300). However, the role of ADP-ribosylation in the prevention of STAT1 phosphorylation has been called into question and it has been suggested that the inhibition of phosphorylation may be the result of sumoylation of STAT1 'Lys-703' (PubMed:29858569). Mono-ADP-ribosylates STAT6; enhancing STAT6-dependent transcription (PubMed:27796300). In macrophages, positively regulates MRC1 expression in response to IL4 stimulation by promoting STAT6 phosphorylation (PubMed:27796300). Mono-ADP-ribosylates PARP9 (PubMed:27796300).\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDomain- and isoform-aware assay design to improve biological interpretation across model systems.\u003c\/li\u003e\n\u003cli\u003eQuantitative workflows emphasizing calibration standards, spike-in controls, and cross-lot comparability.\u003c\/li\u003e\n\u003cli\u003eIn vitro binding\/kinetics profiling (SPR\/BLI) to connect biochemical interactions with cellular phenotypes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMeasure PARP14 enzymatic activity with defined substrates\/cofactors (in vitro assay).\u003c\/li\u003e\n\u003cli\u003eEvaluate inhibitor\/activator effects on PARP14 activity across a concentration series.\u003c\/li\u003e\n\u003cli\u003eQuantify PARP14 using calibration standards in plate-based assays (assay development).\u003c\/li\u003e\n\u003cli\u003eProfile binding interactions of PARP14 by SPR\/BLI (kinetic characterization).\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret results in the context of the biological system, assay format, and any known domain\/isoform constraints for the target.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider species- and isoform-specific differences when comparing results across models or homologs.\u003c\/li\u003e\n\u003cli\u003eFor quantitative assays, include appropriate negative controls and matrix-matched spike-in concepts to assess non-specific signal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProtKB entry (Q460N5) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/Q460N5 - NCBI Gene search (PARP14) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=PARP14 - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=PARP14 - Reactome pathway browser — Reactome: https:\/\/reactome.org\/ - InterPro protein family resource — EMBL-EBI: https:\/\/www.ebi.ac.uk\/interpro\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53059256844653,"sku":"CSB-MP677190HU2-1MG","price":2490.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059358327149,"sku":"CSB-MP677190HU2-100UG","price":344.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059358359917,"sku":"CSB-MP677190HU2-20UG","price":138.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-MP677190HU2-SDS.jpg?v=1772280092","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-protein-mono-adp-ribosyltransferase-parp14-parp14-partial-bhp10514395","provider":"BioHippo","version":"1.0","type":"link"}
