  • 产品描述：
        核糖核酸酶H1（Ribonuclease H1，RNASEH1）是一种核酸酶，主要参与DNA合成中的RNA剪切。RNASEH1的主要功能是在DNA合成时去除RNA片段，确保新合成的DNA链的完整性。这一过程对于维护基因组的稳定性至关重要，因为在DNA合成期间，RNA片段会暂时嵌入新合成的DNA链。
        j9九游会登录入口首页生物提供的重组人RNASEH1蛋白是由大肠杆菌表达系统表达而成的全长重组蛋白。。该产品可用于广泛的分子生物学实验中，特别是在研究DNA合成、RNA剪切和核酸互动等方面。
        RNASEH1在DNA修复和维护基因组完整性中起着重要作用。它的缺陷与一些疾病，如Ataxia Telangiectasia-like Disorder（ATLD）等，有关。因此，研究RNASEH1的结构和功能有助于深入了解DNA代谢的调控机制，同时有助于解析与该酶相关的遗传性疾病的发病机制。j9九游会登录入口首页生物重组RNASEH1蛋白的提供将为科学家在DNA修复、基因组稳定性、疾病发病机制等领域的研究提供有力的支持，促进相关领域的科学进展。

靶点详情

  • 功能：
    Endonuclease that specifically degrades the RNA of RNA-DNA hybrids. Plays a role in RNA polymerase II (RNAp II) transcription termination by degrading R-loop RNA-DNA hybrid formation at G-rich pause sites located downstream of the poly(A) site and behind the elongating RNAp II.
  • 基因功能参考文献：
    1. RNASEH1 gene variants associate with susceptibility/protection to T1 Diabetes in Colombia. PMID: 29204916
    2. Studies indicate that ribonuclease H1 is essential for mitochondrial DNA replication. PMID: 27402764
    3. Data show that the catalytic domains of E. coli and human RNase H have nearly identical sequence preferences, which correlate with the efficiency of RNase H-recruiting antisense oligonucleotides. PMID: 29126318
    4. Data suggest that ribonuclease H1 (RNASEH1) plays important role in replication fork movement by resolving R-loops (RNA-DNA hybrids); RNASEH1 depletion results in accumulation of RNA-DNA hybrids, slowing of replication forks, and increased DNA damage; RNASEH1 appears to contribute to genome stability and preserves telomere integrity. PMID: 28717002
    5. RPA is a sensor of R loops and a regulator of RNaseH1, extending the versatile role of RPA in suppression of genomic instability. PMID: 28257700
    6. RNaseH1 maintains regulated levels of telomeric RNA-DNA hybrids at ALT telomeres to trigger homologous recombination without compromising telomere integrity too severely PMID: 25330849
    7. found that the 3' fragments of target pre-mRNA generated by ASO were almost completely degraded from their 5' ends by nuclear XRN2 after RNase H1-mediated cleavage PMID: 26159921
    8. Altered RNaseH1 has a reduced capability to remove the RNA from RNA-DNA hybrids leading to impaired mtDNA replication and adult-onset mitochondrial encephalomyopathy. PMID: 26094573
    9. RNase H1 and protein P32 are involved in mitochondrial pre-rRNA processing PMID: 23990920
    10. data implicate the H264 side chain in phosphodiester hydrolysis as well as in product release, and are consistent with a proposed model in which the RNAse H1 H264 side chain interacts with a divalent metal ion to support catalysis PMID: 23078533
    11. On the basis of its nuclear magnetic resonance (NMR) nucleic acid structure, a boranophosphonate-modified, fully R(P) BH(3) DNA/RNA hybrid is predicted not to be a substrate for RNase H1. PMID: 21443203
    12. Observational study of gene-disease association. (HuGE Navigator) PMID: 20877624
    13. The cysteine residues responsible for the redox-dependent activity of RNase H1 were determined by site-directed mutagenesis to involve Cys(147) and Cys(148), producing an inactive enzyme conformation by disulfide bond formation. PMID: 12473655
    14. Human RNase H1 uses one tryptophan and two lysines to position the enzyme at the 3'-DNA/5'-RNA terminus of the heteroduplex substrate PMID: 14506260
    15. in human cells RNase H1 is responsible for most of the activity of DNA-like antisense drugs PMID: 14960586
    16. analysis of catalytic site of human RNase H1 for heteroduplex substrate catalysis PMID: 15205459
    17. method for enhancing the human RNase H1 activity of chimeric antisense oligonucleotides PMID: 17028157

    19. Report crystal structures of RNase H1 in complex with RNA/DNA hybrids. PMID: 17964265
    20. Characterization of full-length enzymes with defective hybrid binding domain indicates that this domain dramatically enhances both the specific activity and processivity of RNase H1. PMID: 18337749
