...ry records of achievement. Sharp codiscovered RNA splicing in 1977. This work provided one of the first indications of the startling phenomenon of "discontinuous genes" in mammalian cells. The discovery that genes contain nonsense segments that are edited out by cells in the course of utilizing genetic infor...

New technique provides insights into gene regulation

...ics and Microbiology, who notes out-of-control RNA splicing is involved in many human diseases, including cancers and birth defects. "The new information we can now obtain could also provide insights into new treatments." Each cell in the human body contains about 25,000 genes. Although human tissues and org...

...lls and observe a range of cellular processes. By splicing the genes for the fluorescent proteins into specific genes in the cell, researchers can detect when those genes are switched on to produce proteins. They can then use the telltale fluorescent colors to separate the cells visually. The availability of...

Multi-purpose protein regulates new protein synthesis and immune cell development

...hat IRE1 triggers the unfolded protein response by splicing a segment of messenger RNA called XBP1. This leads to production of a new protein, which turns on genes in the UPR signaling pathway and directs cells to secrete large amounts of protein. The University of Michigan has filed a U.S. patent application...

Researchers find missing genes of ancient organism

...nes for tRNA in an ancient parasite are made up by splicing together sequences in distant parts of the DNA genome. The research led by Professor Dieter Sll in the Department of Molecular Biophysics and Biochemistry at Yale focuses on the most ancient organism with a known genome sequence. Nanoarchaeum equ...

Alternative splicing is emerging as a key mechanism for controlling cellular function, and identification of MMPs as influencing these processes provides a unique tool for understanding their regulation." Finding new mechanisms of cancer control can lead to specific o...

Modification of program enables prediction of gene transcription

...xtra-long untranslated region is then discarded by splicing the 5' untranslated region (UTR). All present gene finding systems except for N-SCAN either ignore the UTR splice sites or incorrectly incorporate them into some protein-coding segment, making gene prediction a none-too-sure industry. "We...

This longer form of Apoer2 is necessary for reelin to act upon the NMDA receptor, Dr. Herz and his colleagues found. When reelin binds to the longer Apoer2, the NMDA receptor alters its structure an...
