To sleep, perchance to dream: New insight into melatonin production

...NAT mRNA translation is mediated by IRES (internal ribosome entry site) elements in the 5' end of the transcript, through binding of another protein, called hnRNP Q. In fact, siRNA knock-down of hnRNP Q reduced AANAT and melatonin production under nocturnal conditions. ...

Regulating the nuclear architecture of the cell

...e organization and structure of the nucleolus, the ribosome factory, which is situated at the specific site in the heterochromatin where ribosomal DNA -- consisting of large genes, repeated 300 to 400 times -- codes for the production of the RNA from which ribosomes are built. "This work on pathways tha...

Basic work on E. coli identifies two new keys to regulation of bacterial gene expression

...se. "By understanding transcription and control of ribosome synthesis in E. coli, we can understand more about these processes in bacterial species that we need to control, like those that cause disease or make toxins. E. coli is also the workhorse of the biotechnology industry. Understanding E. coli gene exp...

New method for identifying microbes

...eginning of the gene that codes for a piece of the ribosome -- the highly conserved "single point" reference gene. By sequencing these tags and comparing the sequenced code with databases of known bacterial genomes, the Brookhaven team determined that this specific 16-letter region contains enough unique gene...

Biotechnology's newest chemical tool

...application might be to label various sites in the ribosome -- the RNA-based site of protein production -- with bright fluorophores using appropriate RNA methyltransferases, enabling real-time dynamic studies of the complicated mechanism of protein translation. ...

Study provides insight into cellular defenses against genetic mutation

... mRNAs linked to CBP80 are targeted for NMD when a ribosome finds an early stop codon. Most recently, the Nature paper demonstrated for the first time that CBP80 works by activating a protein factor known to drive NMD called human up-frameshift (hUpf) protein 1. A Matter of Spacing Immature mRNA is made ...

Life's origins were easier than was thought

... are called ribozymes (a contraction of the words ribosome and enzyme). But there is an important obstacle to the theory of ribozymes as the origin of life: they could not be very large in length as they would not be able to correct the replication errors (mutations). Therefore they were unable to contain en...
