Regulation of gene expression in trypanosomatids: living with polycistronic transcription

C Clayton - Open biology, 2019 - royalsocietypublishing.org
In trypanosomes, RNA polymerase II transcription is polycistronic and individual mRNAs are
excised by trans-splicing and polyadenylation. The lack of individual gene transcription …

Codon usage bias controls mRNA and protein abundance in trypanosomatids

The zinc finger proteins ZC3H20 and ZC3H21 stabilise mRNAs encoding membrane proteins and mitochondrial proteins in insect‐form Trypanosoma brucei

B Liu, K Kamanyi Marucha, C Clayton - Molecular microbiology, 2020 - Wiley Online Library
Abstract ZC3H20 and ZC3H21 are related trypanosome proteins with two C (x) 8C (x) 5C (x)
3H zinc finger motifs. ZC3H20 is present at a low level in replicating mammalian‐infective …
