Expression of IE1 and IE2 proteins is critical for the establishment of lytic infection and reactivation from viral latency. Disrupts PML-associated ND10 nuclear bodies by interfering with host PML and SP100 sumoylation thereby altering the regulation of type I and type II interferon-induced gene expression. Promotes efficient viral growth by interacting with and directing host SP100 to degradation, leading to enhanced acetylation level of histones. In addition, functions in counteracting the host innate antiviral response. Inhibits the type I interferon pathway by directly interacting with and sequestrating host STAT2. Also targets type II interferon pathway by repressing IL6- and STAT3 target genes. Repression of STAT3 genes is due to STAT3 nuclear accumulation and disruption of IL6-induced STAT3 phosphorylation by IE1. This repression is followed by phosphorylation and activation of STAT1. Inhibits host ISG transcription by sequestering host ISGF3 in a PML- and STAT2- binding dependent manner. Alters host cell cycle progression, probably through its interaction with host E2F1 or RB1 that overcomes the RB1-mediated repression of E2F-responsive promoters.. When interpreting results, consider species context, domain architecture, and whether the recombinant format represents full-length or a defined region.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAntigen and virulence-factor studies that compare strain- or domain-specific binding and immune recognition.\u003c\/li\u003e\n\u003cli\u003eUse of recombinant proteins as standards for quantitative assays and serology-oriented method development.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBinding and interaction assays:\u003c\/strong\u003e quantify partner binding and rank conditions using plate-based formats or biophysical methods (SPR\/BLI).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCell-based functional studies:\u003c\/strong\u003e evaluate dose–response and time-course effects in relevant cell systems when the target acts extracellularly or through receptor engagement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssay development:\u003c\/strong\u003e use as a standard, spike-in control, or positive control where consistent specifications are required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpretation typically relies on relative comparisons (treated vs control, mutant vs wild-type, or dose\/time series) using consistent sample handling and appropriate normalization.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost-translational modifications:\u003c\/strong\u003e expression system can affect glycosylation and processing; interpret differences cautiously when comparing to native protein.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsoforms and domains:\u003c\/strong\u003e expressed regions may not capture all isoform-specific features; match fragment boundaries to your assay’s binding site.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e include blank matrix controls, tag-only controls (where relevant), and orthogonal readouts (e.g., WB\/qPCR\/ELISA) to support interpretation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProt Knowledgebase entry for HAPLN1 — UniProt — https:\/\/www.uniprot.org\/ - NCBI Gene for HAPLN1 — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/ - RCSB Protein Data Bank — RCSB PDB — https:\/\/www.rcsb.org\/ - PubMed (reviews and primary literature) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/ - Ensembl gene summary — Ensembl — https:\/\/www.ensembl.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53058984378733,"sku":"CSB-EP010130HUe1-1MG","price":2632.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059075866989,"sku":"CSB-EP010130HUe1-100UG","price":744.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059075899757,"sku":"CSB-EP010130HUe1-20UG","price":472.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP010130HUe1-SDS.jpg?v=1772271011","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-hyaluronan-and-proteoglycan-link-protein-1-hapln1-bhp10511373","provider":"BioHippo","version":"1.0","type":"link"}
