New methods reveal that complex local splicing variations are more prevalent in animals than previously appreciated, and demonstrate that local splicing variations are relevant for studies of development, gene regulation and neurodegenerative diseases.
Viewing the dynamic interactions of individual spliceosomal subcomplexes with single pre-messenger RNA molecules reveals how nearby flanking splice sites accelerate pre-spliceosome assembly and the splicing of multi-intron pre-mRNAs.
The RNA-binding protein polypyrimidine tract-binding protein 1 (PTBP1) is essential for B cell development at the pro-B cell stage where it suppresses S-phase entry and promotes progression through mitosis.
Differential eIF4E binding to transcription initiation nucleotides and alternative promoter usage of eIF1A, PABP and other genes are involved in the response of the translation machinery to energy stress.
Single-cell mRNA sequencing on hemocytes of penaeid shrimp revealed six types of hemocytes, type markers, differentiation pathways, and different immune roles among these subpopulations based on their transcriptional profiles.
Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.
