A collaborative project between American and Chinese researchers developed a way to study the function of genes in mice and man by using a moveable genetic element from moths, according to a report in the journal Cell.
"We know how many genes are in the mammalian genome, but that does not tell us how they carry out their jobs," said senior author Tian Xu, Professor and Vice Chair of Genetics at Yale University School of Medicine and a Howard Hughes Medical Institute Investigator. "We have found a way to systematically inactivate genes in the mouse genome so we can understand the functions of these genes."
After sequencing the human and mouse genomes, many scientists have shifted their attention to determining the function of all of those genes. The strategy is to mutate each gene, to observe the consequences, and investigate the molecular mechanisms. In the past two decades, only a small percentage of the genes shared by mice and humans have been analyzed in detail.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
