Stowers Institute's Baumann Lab identifies key step in maturation pathway of telomerase

...end of the telomerase RNA subunit," said Jessica Box, Research Technician I and co-equal first author on the paper. "It was highly unexpected that the spliceosome could have such a function, as the two steps of removing an internal piece of RNA and gluing the flanking ends together are tightly coupled during int...

Spliceosome in Biological Definition

Spliceosome

A spliceosome is a complex of RNA and many protein subunits, that remove the non-coding introns from unprocessed mRNA . The mRNA of prokaryotes is simpler, and they do not have introns, so only eukaryotes have spliceosomes. The RNAs that spliceosomes consist of are named U1, U2, U4, U...

Spliceosome

A spliceosome is a complex of specialized RNA and protein subunits that removes introns from a transcribed pre-mRNA (hnRNA) segment. This process is generally referred to as splicing. spliceosome ( ) n. A nucleoprotein particle that aids in the splicing of messenger RNA in eukaryotes ...
