U1 snRNP complex with cleavage and polyadenylation factors controls mRNA transcription termination
Full-length transcription in the majority of human genes depends on U1 snRNP (U1) to co-transcriptionally suppress transcription-terminating premature 3’-end cleavage and polyadenylation (PCPA) from cryptic polyadenylation signals (PASs) in introns. However, the mechanism of this U1 activity, termed telescripting, is unknown. Here, we captured a complex, comprising U1 and CPA factors (U1–CPAFs), that binds intronic PASs and suppresses PCPA. U1–CPAFs are distinct from U1-spliceosomal complexes; t...

Deep data QC
72/100 · CStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
The C grade is a transparent weighted average. Each metric below scored from 0–100% against the published bulk-RNA-seq thresholds, weighted by its importance; nothing is hidden or subjective.
