Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have made a major discovery in how human cells produce energy. Their study, published in The EMBO Journal, reveals ...

Human mitochondrial transcripts contain messenger and ribosomal RNAs flanked by transfer RNAs (tRNAs), which are excised by mitochondrial RNase (mtRNase) P and Z to liberate all RNA species. In ...

Canonical RNA processing in mammalian mitochondria is defined by tRNAs acting as recognition sites for nucleases to release flanking transcripts. The relevant factors, their structures, and mechanism ...

The ribosome, that protein-making machine, relies on other, smaller machines. For example, it works in concert with a mechanism that supplies amino-acid-carrying tRNAs, including tRNAs that require ...

Collaborative research by the University of Tokyo and RIKEN Center for Biosystems Dynamics Research has led to the development of a new method for simultaneously synthesizing all transfer RNA (tRNA) ...

A team of researchers from Mass General Brigham led by Raghu Chivukla, MD, PhD released a new study linking protein aggregation to altered RNA processing in genetic forms of neurodegeneration.

The fruit fly lacks the tRNA nuclear export receptor Exportin-t, which only exports end-processed tRNAs to the cytoplasm to ensure the completion of the processing steps in the nucleus. The related ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...

To build proteins, cells rely on a molecule called transfer RNA, or tRNA. tRNAs act like protein-building couriers, where they read the genetic instructions from messenger RNA, mRNA, and deliver the ...
