The UniProt recommended name is U7 small nuclear RNA-associated Sm-like protein LSM11 (LSM11). This protein functions as part of a specialized LSM complex that recognizes U7 snRNA, forming the U7 small nuclear ribonucleoprotein (snRNP) complex involved in 3'-end processing of replication-dependent histone transcripts.\u003cbr\u003e\u003cbr\u003eFunctionally, LSM11 antibody identifies a 383-amino-acid nuclear protein that partners with LSM10 and other U7 snRNP components to direct histone mRNA 3'-end cleavage. Unlike polyadenylated transcripts, replication-dependent histone mRNAs end in a conserved stem-loop followed by a purine-rich histone downstream element (HDE). The LSM11-containing U7 snRNP recognizes this sequence and recruits the histone cleavage complex to generate mature histone mRNA. This process ensures tight coupling of histone production to DNA replication during S phase.\u003cbr\u003e\u003cbr\u003eThe LSM11 gene is located on chromosome 5q35.3 and encodes a nuclear-localized protein expressed in proliferating cells, where histone synthesis is active. LSM11 contains Sm motifs that mediate RNA binding and protein-protein interactions essential for snRNP assembly. It directly interacts with FLASH (FLICE-associated huge protein) and the histone cleavage complex subunits to coordinate endonucleolytic processing of histone pre-mRNAs.\u003cbr\u003e\u003cbr\u003eBeyond its canonical role in histone RNA processing, LSM11 contributes to transcriptional regulation and genome stability. It has been implicated in the activation of p53-dependent apoptosis under replication stress conditions through the U7 snRNP-FLASH pathway. By modulating histone synthesis, LSM11 indirectly affects chromatin assembly and DNA packaging during cell division. Perturbation of LSM11 expression leads to cell cycle arrest, defective chromatin condensation, and genomic instability.\u003cbr\u003e\u003cbr\u003eLSM11 antibody is widely used in molecular biology, RNA processing, and cell cycle research. It is suitable for immunoblotting, immunofluorescence, and RNA-protein interaction studies to examine LSM11 localization and function. This antibody supports research into histone mRNA metabolism, snRNP assembly, and nuclear RNA processing mechanisms. In cancer and developmental studies, LSM11 detection aids in investigating how histone synthesis regulation impacts proliferation and differentiation.\u003cbr\u003e\u003cbr\u003eStructurally, LSM11 shares the characteristic Sm-fold found in RNA-binding LSM proteins, forming ring-like complexes that interact with U7 snRNA. Its N-terminal region is important for FLASH recruitment, while the C-terminal domain stabilizes the U7 snRNP.\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\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=LSM11 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=LSM11 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=LSM11 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/LSM11 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=LSM11+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":53047310123373,"sku":"FY13034","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_d2436300-1dc7-4f7f-9dc7-b7b12f63a1a8.jpg?v=1782237063","url":"https:\/\/www.ebiohippo.com\/products\/lsm11-antibody-u7-snrna-associated-sm-like-protein-lsm11-bha17135936","provider":"BioHippo","version":"1.0","type":"link"}
