EXPORT MECHANISM: The tRNA must mature inside the nucleus before export. tRNAs are aminoacylated, and only tRNAs charged with an amino acid are exported efficiently. Export occurs when the tRNA is ...

Collaborative research by the University of Tokyo and RIKEN Center for Biosystems Dynamics Research has led to the ...

Scientists have uncovered key new information towards understanding the crucial first step in protein synthesis, the process by which the genetic code, harbored within DNA and copied into RNA, is ...

Rush hour never ceases at the nucleus’ border. Gene products begin their lives in the nucleus as strands of mRNA that ship out into the cytoplasm, where they serve as templates for protein synthesis.

This narrated animation illustrates the process of protein synthesis, starting with chromosomal DNA inside the cell's nucleus. A gene is transcribed into messenger RNA, which leaves the nucleus and ...

An international team of scientists have used advanced microscopy to image how ribosomes recruit to mRNA. Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell ...

Ribosome Assembly: New research shows that neurons not only synthesize proteins locally near synapses. They can also assemble ribosomes at synapses. Dynamic Regulation: Local ribosome maturation ...

Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through ...

When a bone grows, our bodies’ proteins help provide the structure. When a muscle tears, proteins help rebuild it. When we fight an infection, transport oxygen in our blood or send messages to a cell, ...
