  1. ...KRAB zinc-finger proteins regulate endogenous retroviruses to sculpt germline transcriptomes and evolution Kai Otsuka1,2, Akihiko Sakashita3,4, So Maezawa2, Richard M. Schultz1,5 and Satoshi H. Namekawa1,3 1Department of Microbiology and Molecular Genetics, University of California, Davis...
  2. ...contributed equally to this work. Corresponding authors: jnw72@cornell.edu, cf458@cornell.eduAbstractCys2-His2 zinc finger genes (ZNFs) form the largest family of transcription factors in metazoans. ZNF evolution is highly dynamic and characterized by the rapid expansion and contraction of numerous...
  3. ...). KZFPs are characterized by an N-terminal KRAB domain and a C-terminal array of zinc fingers (ZFs) conferring sequence-specific polynucleotide binding potential. Sequence specificity is conferred by three amino acids within each ZF interacting with a triplet of bases in the polynucleotide target...
  4. ...number of genomic mutations in just a few cell cycles. In contrast, despite clear deaminase activity and DNA damage, APOBEC3B upregulation does not generate a significant increase in mutations in the gastric epithelium. APOBEC3B-associated mutagenesis remains minimal even in the context of TP53...
  5. ...silenced by KRAB zinc finger (KZNF) proteins recruiting corepressor proteins that establish a repressive chromatin state. A number of KZNFs have been reported to bind SVAs, but their individual contribution to repressing SVAs and their roles in suppressing SVA-mediated gene-regulatory effects remains...
  6. ...@mail.hzau.edu.cn, limaoteng426@hust.edu.cnAbstractThe recently constructed mutant libraries of diploid crops by the CRISPR-Cas9 system have provided abundant resources for functional genomics and crop breeding. However, because of the complexity, it is a big challenge to accomplish large-scale targeted mutagenesis...
  7. ...implicated in the regulation of diverse biological processes, including spermatogenesis, heat shock response, ultraviolet-induced DNA damage response and maternal mRNA clearance. Despite the recognized significance of m6A in mRNA regulation, limited studies have focused on the targeted and efficient...
  8. ...-scale mutagenesis to other nonmodel organisms.ResultsDesign and construction of the CRISPR single-guide RNA libraryBased on our previously reported, highly efficient, CRISPR-Cas9-mediated B. mori targeted mutagenesis in the whole animal and the pooled library in cultured cells (Ma et al. 2014a; Chang et...

Nature 445: 379–381. Meng X, Noyes MB, Zhu LJ, Lawson ND, Wolfe SA. 2008. Targeted gene inactivation in zebrafish using engineered...
  10. .... 2017). Furthermore, physical interference between multiple chiasmata may lead to regional differences in recombination rate (Gray and Cohen 2016; Peñalba and Wolf 2020). The zinc-finger protein encoded by the gene PRDM9 has been described as an important regulator of recombination in some species...
