TranscriptomicsCleavage Factor Im as a key regulator of 3’ UTR length
In eukaryotes, the 3' ends of RNA polymerase II-generated transcripts are made in the majority of cases by site-specific endonucleolytic cleavage, followed by the addition of a poly(A) tail. By alternative polyadenylation, a gene can give rise to multiple mRNA isoforms that differ in the length of t...

TranscriptomicsCas9 target DNA specificity in vitro and in vivo (S. cerevisiae)
Cas9, a CRISPR RNA-guided nuclease, has been rapidly adopted as a tool for biochemical and genetic manipulation of DNA. Although Cas9 offers remarkable specificity and versatility for genome manipulation, mis-targeted events occur. To extend the understanding of Cas9 target::homology requirements, w...

ProteomicsSnake venom serine proteinases specificity mapping by proteomic identification of cleavage sites
Serine proteinases have been shown to play the role of toxins in the venoms of many snakes. They act mainly on components of the coagulation cascade, and fibrinolytic and kallikrein-kinin systems to trigger various pathological effects observed in the envenomation. Despite showing high similarity in...

TranscriptomicsGenome?wide analysis of pre?mRNA 3' end processing reveals a decisive role of human cleavage factor I in the regulation of 3' UTR length: A-seq
Through alternative polyadenylation, human mRNAs acquire longer or shorter 3' untranslated regions, the latter typically associated with higher transcript stability and increased protein production. To understand the dynamics of polyadenylation site usage, we mapped transcriptome?wide both binding s...

ProteomicsActive Site Specificity Profiling of the Matrix Metalloproteinase Family: Proteomic Identification of 4,300 Cleavage Sites by MMPs 1, 2, 3, 7, 8, 9, 12, 13, and 14.
Background: The active site of matrix metalloproteinases (MMPs) is highly conserved, complicating the rational design of specific substrates and inhibitors for individual family members. Results: Active site specificity profiles of 9 MMPs were determined using high throughput Proteomic Identificatio...

ProteomicsEnhanced Proteomics Analysis with a Novel Recombinant Chymotrypsin Analogue En-gineered for High Cleavage Specificity
Chymotrypsin is widely used in shotgun proteomics owing to its orthogonal cleavage specificity relative to trypsin, which enhances sequence coverage of hydrophobic protein regions. However, commercial preparations often display variable cleavage specificity, trypsin contamination, and elevated misse...

GenomicsA genome-wide analysis of Cas9 binding specificity using ChIP-seq and targeted sequence capture
Clustered regularly interspaced short palindromic repeat (CRISPR) RNA-guided nucleases have gathered considerable excitement as a tool for genome engineering. However, questions remain about the specificity of their target site recognition. Most previous studies have examined predicted off-target bi...
