LUC7 proteins play crucial role in efficient RNA splicing

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns, are cut out and the coding portions are spliced back together.
