RNA processing: Fungal spliceosomes break the mold

Curr Biol. 2021 Nov 22;31(22):R1482-R1484. doi: 10.1016/j.cub.2021.09.075.

Abstract

Dozens of splicing factors work together in human cells to remove introns from nascent RNA transcripts. A new study reveals that spliceosomes from many distantly related fungal species are surprisingly similar to those found in human cells.
