Frequency-modulated nuclear localization bursts coordinate gene regulation [PDF]

open access: yes, 2008
In yeast, the transcription factor Crz1 is dephosphorylated and translocates into the nucleus in response to extracellular calcium. Here we show, using time-lapse microscopy, that Crz1 exhibits short bursts of nuclear localization (typically lasting 2 ...

Structural basis underlying viral hijacking of a histone chaperone complex

open access: yesNature Communications, 2016
The Epstein-Barr virus tegument protein BNRF1 is required for the establishment of selective viral gene expression during latency and interacts with the histone chaperone DAXX.

The human lncRNA LINC-PINT inhibits tumor cell invasion through a highly conserved sequence element

open access: yesGenome Biology, 2017
Background It is now obvious that the majority of cellular transcripts do not code for proteins, and a significant subset of them are long non-coding RNAs (lncRNAs).

Weighted-Lasso for Structured Network Inference from Time Course Data [PDF]

open access: yes, 2009
We present a weighted-Lasso method to infer the parameters of a first-order vector auto-regressive model that describes time course expression data generated by directed gene-to-gene regulation networks. These networks are assumed to own a prior internal

Optimal first-passage time in gene regulatory networks

open access: yes, 2014
The inherent probabilistic nature of the biochemical reactions, and low copy number of species can lead to stochasticity in gene expression across identical cells.

Multi-locus CRISPRi targeting with a single truncated guide RNA

open access: yesNature Communications
A critical goal in functional genomics is evaluating which non-coding elements contribute to gene expression, cellular function, and disease. Functional characterization remains a challenge due to the abundance and complexity of candidate elements. Here,

The Penn State Protein Ladder system for inexpensive protein molecular weight markers

open access: yesScientific Reports, 2021
We have created the Penn State Protein Ladder system to produce protein molecular weight markers easily and inexpensively (less than a penny a lane). The system includes plasmids which express 10, 15, 20, 30, 40, 50, 60, 80 and 100 kD proteins in E. coli.

One-two punch mechanism of gene repression: a fresh perspective on gene regulation. [PDF]

open access: yes, 2017
Cellular differentiation depends on temporally controlled waves of gene activation and inactivation that ultimately transform one cell type into another.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

AGO-bound mature miRNAs are oligouridylated by TUTs and subsequently degraded by DIS3L2

open access: yesNature Communications, 2020
3′ end of microRNAs binds to the PAZ domain of Argonaute (AGO) proteins. Here the authors show that terminal nucleotidyltransferases TUT4/7 and exonuclease DIS3L2 induce tailing and decay of 3’ end exposed-microRNAs in AGO PAZ mutant expressing- or ...
