Researchers solve structure of human protein critical for silencing genes
In a study published in the journal Cell on May 24, Cold Spring Harbor Laboratory (CSHL) scientists describe the three-dimensional atomic structure of a human protein bound to a piece of RNA that "guides" the pr ...

Real-time monitoring of RNA splicing in living cells moves step closer with novel fluorescent probe
Numerous biological processes depend on molecules called lariat RNAs (LaRNAs). These lasso-shaped structures form in the cell during RNA splicing. During this process, transcribed RNA strands convert to messenger ...

MIT biologist relishes the challenge of picking apart the cell's most complex structure
One of the most important structures in a cell is the nuclear pore complex — a tiny yet complicated channel through which information flows in and out of the cell’s nucleus, directing all other cell ...

Researchers reveal an RNA modification influences thousands of genes
Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics ...

Study reveals how ribosomes override their blockades
Ribosomes are "protein factories" in the cells of all living things. They produce proteins based on existing genetic codes stored on special nucleic acid molecules. These molecules, also called messenger RNA (mRNA) due to ...

Research uncovers new exception to decades-old rule about RNA splicing
There are always exceptions to a rule, even one that has prevailed for more than three decades, as demonstrated by a Cold Spring Harbor Laboratory (CSHL) study on RNA splicing, a cellular editing process. The rule-flaunting ...

Research reveals novel transport mechanism for large ribonucleoproteins
The movement of genetic materials, such as RNA and ribosomes, from the nucleus to the cytoplasm is a critical component in a cell's ability to make the proteins necessary for essential biological functions. Until now, it ...

It's a trap! New laboratory technique captures microRNA targets
Human cells are thought to produce thousands of different microRNAs (miRNAs)—small pieces of genetic material that help determine which genes are turned on or off at a given time. miRNAs are an important ...
