Order of removal of conventional and nonconventional introns from nuclear transcripts of Euglena gracilis. [PDF]
PLoS Genetics, 2018 Nuclear genes of euglenids and marine diplonemids harbor atypical, nonconventional introns which are not observed in the genomes of other eukaryotes. Nonconventional introns do not have the conserved borders characteristic for spliceosomal introns or the

Monte Carlo simulations of the inside-intron recombination [PDF]
, 2005 Biological genomes are divided into coding and non-coding regions. Introns are non-coding parts within genes, while the remaining non-coding parts are intergenic sequences. To study the evolutionary significance of recombination inside introns we have used two models based on the Monte Carlo method.

Origin of spliceosomal introns and alternative splicing.
Cold Spring Harbor Perspectives in Biology, 2014 In this work we review the current knowledge on the prehistory, origins, and evolution of spliceosomal introns. First, we briefly outline the major features of the different types of introns, with particular emphasis on the nonspliceosomal self-splicing ...

An orchestrated intron retention program in meiosis controls timely usage of transcripts during germ cell differentiation [PDF]
, 2017 Global transcriptome reprogramming during sper-matogenesis ensures timely expression of factors in each phase of male germ cell differentiation. Sper-matocytes and spermatids require particularly exten-sive reprogramming of gene expression to switch from

Minimal Introns Are Not “Junk” [PDF]
Genome Research, 2002 Intron-size distributions for most multicellular (and some unicellular) eukaryotes have a sharp peak at their “minimal intron” size. Across the human population, these minimal introns exhibit an abundance of insertion-deletion polymorphisms, the effect of which is to maintain their optimal size.

FEBS Letters, EarlyView.Glutaredoxin (Grx) 3 proteins contain a thioredoxin domain and one to three class II Grx domains. These proteins play a crucial role in iron homeostasis in eukaryotic cells. In human Grx3, at least one of the two Grx domains, together with the thioredoxin domain, is essential for its function in iron metabolism.

Handling tRNA introns, archaeal way and eukaryotic way
Frontiers in Genetics, 2014 Introns are found in various tRNA genes in all the three kingdoms of life. Especially, archaeal and eukaryotic genomes are good sources of tRNA introns that are removed by proteinaceous splicing machinery.

Presence of multiple group I introns closely related to bacteria and fungi in plastid 23S rRNAs of lichen-forming Trebouxia [PDF]
, 2009 The chloroplast-encoded large subunit ribosomal RNA gene of several free-living green algae contains group I introns at Escherichia coli genic positions 1917, 1931, 1951, and 2449.
