Each miRNA gene produces at least three small RNA species, including a long primary miRNA transcript (pri-miRNA), an intermediate ∼60-nt precursor miRNA (pre-miRNA), and a ∼21-nt mature miRNA, through sequential endonucleolytic maturation steps [2].
Nanobodies are in vivo affinity matured entities that do not need in vitro affinity maturation steps as are often required with binders from naive or synthetic libraries.
Although total RNA-seq has been shown to provide insight into ongoing transcription and co-transcriptional splicing in the nucleus [ 14, 20], the simultaneous presence of mature RNAs from the cytoplasm confounds the analysis of nuclear RNA maturation steps.
Northern experiments demonstrated that the gene is expressed in ascomata sampled at different maturation steps.
Most factors involved in these RNA maturation steps have remained elusive for a long time.
Variables in DC-based product design include the type of antigenic payload used, DC maturation steps and activation processes, and functional assays.
In addition to translation regulation, several other mRNA maturation steps and events, including mRNA splicing, polyadenylation and localization, have been shown to be influenced by the presence of these RNA G-quadruplexes.
These data suggest that Rio2 could play a central role in regulating cytoplasmic maturation steps.
Introns and their splicing are tightly coupled with the subsequent mRNA maturation steps, especially nucleocytoplasmic export.
In the endoplasmic reticulum (ER), critical protein maturation steps including N-glycosylation and disulfide-bond formation take place.
However, the cellular site(s) of this step in snRNP biogenesis and the timing with respect to other maturation steps are not well defined.
