Latest Minor spliceosome Stories
Certain diseases such as cystic fibrosis and muscular dystrophy are linked to genetic mutations that damage the important biological process of rearranging gene sequences in pre-messenger RNA, a procedure called 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.
Fetuses with defects in a molecular machine that edits information cells use to make proteins can develop a rare form of dwarfism.
DNA was originally thought to have a single function: to help cells make the proteins they need.
Using a new approach to studying the spliceosome, a team led by University of Michigan chemistry and biophysics professor Nils Walter, collaborating closely with a team led by internationally recognized splicing experts John Abelson and Christine Guthrie of the University of California, San Francisco, spied on the splicing process in single molecules.
Two molecular biologists at Cold Spring Harbor Laboratory have uncovered important new details about how a gene mutation causes a cellular editing error that results in a devastating disease called pontocerebellar hypoplasia (PCH).
An international research team led by Tim Nilsen, Ph.D., a professor of medicine and biochemistry and the director of the School of Medicine's Center for RNA Molecular Biology, has discovered an unexpected mechanism governing alternative splicing, the process by which single genes produce different proteins in different situations. The new mechanism suggests that curing the more than half of genetic diseases that are caused by mutations in the genetic code that in turn create mistakes in...
The discovery in 1977 that the coding regions of a gene could appear in separate segments along the DNA won the 1993 Nobel Prize in Physiology or Medicine for Richard J. Roberts and Phillip A. Sharp. The active segments of a gene were termed exons, separated from each other within the gene by inactive introns.
Pre-messenger RNA (pre-mRNA) splicing is an integral step in gene expression, removing introns that would otherwise disrupt the coding potential of gene transcripts.
