The catalytic center of the ribosome, known as the peptidyl transferase center (PTC), is composed entirely of rRNA. The PTC is highly conserved across all domains of life, highlighting the fundamental ...

Researchers have developed a new microscopy technique to observe how ribosomes function in cells. With this method, they can monitor individual ribosomes as they convert mRNA into proteins.

Right open reading frame kinase 2 (RIOK2) plays an essential role in ribosome assembly and cell growth, survival and stress responses. Research has linked RIOK2 to tumor progression and poor prognosis ...

Ribosomes getting stuck The team also made an important discovery about ribosome collisions—where one ribosome runs into another due to a tricky RNA segment or differences in speed, for example ...

A study reveals why this assembly often begins during the very ... They are produced by the ribosome, a cellular ''machine'' that reads the instructions contained in messenger RNAs.
