연구실 소개
장혜식 교수의 연구실은 전사체 및 RNA 가공 메커니즘을 고해상도로 분석하는 데 초점을 맞추고 있습니다. 특히 SARS-CoV-2와 같은 바이러스의 전사체 구조와 폴리(A) 꼬리 조절 메커니즘을 밝혀내기 위한 고용량 시퀀싱 기반의 신속한 분석 기법을 개발하고 있습니다. 이와 더불어, mRNA의 폴리(A) 꼬리 변화가 유전자 발현 조절에 미치는 영향을 다각도로 연구하며, 생물학적 샘플의 미량에서도 정밀하게 RNA 꼬리 분석이 가능한 TAIL-seq 및 Tailseeker 소프트웨어 플랫폼을 선도적으로 개발해왔습니다.

15The severe acute respiratory coronavirus 2 (SARS-CoV-2), which emerged in December 2019 in Wuhan, China, has spread rapidly to over a dozen countries. Especially, the spike of case numbers in South Korea sparks pandemic worries. This virus is reported to spread mainly through person-to-person contact via respiratory droplets generated by coughing and sneezing, or possibly through surface contaminated by people coughing or sneezing on them. More critically, there have been reports about the possi
Eukaryotic mRNAs are subject to multiple types of tailing that critically influence mRNA stability and translatability. To investigate RNA tails at the genomic scale, we previously developed TAIL-seq, but its low sensitivity precluded its application to biological materials of minute quantity. In this study, we report a new version of TAIL-seq (mRNA TAIL-seq [mTAIL-seq]) with enhanced sequencing depth for mRNAs (by ∼1000-fold compared with the previous version). The improved method allows us to
Summary SARS-CoV-2 is a betacoronavirus that is responsible for the COVID-19 pandemic. The genome of SARS-CoV-2 was reported recently, but its transcriptomic architecture is unknown. Utilizing two complementary sequencing techniques, we here present a high-resolution map of the SARS-CoV-2 transcriptome and epitranscriptome. DNA nanoball sequencing shows that the transcriptome is highly complex owing to numerous recombination events, both canonical and noncanonical. In addition to the genomic RNA

Remove U3 and 7SL RNAs from contaminant database pipeline. Fix the compatibility issue with recent versions of snakemake. Add support for MiSeq v3 chemistry. Fix a crash issue in tailseq-dedup-perfect when it fails if more than 1024 alignments with less optimal TAIL-seq signals are followed after an alignment wi
Tailseeker 3.1 is a software suite for profiling RNA poly(A) tails with a high-throughput DNA sequencer. This pre-built resource package contains the genome indices, gene annotations, and gene association databases processed to be used with Tailseeker. The data were built with ENSEMBL GRCh38 <em>(H. sapiens)</em> as of Dec 15, 2016. The whole reference database for human was uploaded as two parts. Please download doi:10.5281/zenodo.203943 too.
