RNA dicing promotes the expression of an oncogenic JAK1 isoform

Key Points

• This research aims to understand how RNA dicing affects the expression of different JAK1 isoforms, particularly an oncogenic variant.
• Analyzed RNA dicing effects on JAK1 mRNA
• Investigated the generation of truncated mRNAs
• Examined the functional implications of oncogenic isoform expression
• RNA dicing produced uncapped truncated mRNAs
• Identified a functional independent JH1 kinase domain
