Affinity Capture-RNA

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and associated RNA species identified by Northern blot, RT-PCR, affinity labeling, sequencing, or microarray analysis.

Surveillance of 3' mRNA cleavage during transcription termination requires CF IB/Hrp1.

Li J, Querl L, Coban I, Salinas G, Krebber H

CF IB/Hrp1 is part of the cleavage and polyadenylation factor (CPF) and cleavage factor (CF) complex (CPF-CF), which is responsible for 3' cleavage and maturation of pre-mRNAs. Although Hrp1 supports this process, its presence is not essential for the cleavage event. Here, we show that the main function of Hrp1 in the CPF-CF complex is the nuclear mRNA quality control ...
