miRNA levels depend on both biogenesis and turnover. The methyltransferase HEN1 stabilizes plant miRNAs, animal piRNAs, and siRNAs in both kingdoms via 3' terminal methylation. Loss of HEN1 in plants results in non-templated oligo-uridylation and accelerated degradation of miRNAs. In hen1 mutants fr...
ORGANISM(S): Arabidopsis thaliana 
We recently discovered that human neutrophils express immunomodulatory glycoproteins carrying unusual and highly truncated paucimannosidic N-glycans (Man1-3GlcNAc2Fuc0-1), but their biosynthesis remains elusive. Guided by the well-characterised truncation pathway in invertebrates and plants in which...

Truncation of the p300/CBP TAZ2 domain promotes tumor progression
Many thousand long non-coding (lnc) RNAs are mapped in the human genome. Time consuming studies using reverse genetic approaches by post-transcriptional knock-down or genetic modification of the locus demonstrated diverse biological functions for a few of these transcripts. The Human Gene Trap Mutan...

Cas9-guided haplotyping of three truncation variants in autosomal recessive disease
RNA-seq analysis of the budding yeast prp45(1-169) strain (a "scarless" truncation)
The histone acetyltransferase activity of p300/CBP is negatively regulated by the TAZ2 domain. Truncating mutations in the TAZ2 domain have been identified in several cancer types. Here, we show that truncation of p300/CBP at the TAZ2 domain inhibits tumor cell growth in vitro, while accelerating tu...
