Population

In vitro mRNA decay system using cell extracts and polyadenylated mRNAs (beta-globin, chloramphenicol acetyltransferase, and simian virus 40 virion proteins)

Intervention

Depletion of functional PABP (via excess poly(A) competitor or poly(A)-Sepharose column) and addition of purified Saccharomyces cerevisiae or human cytoplasmic PABP

Comparator

Reactions containing excess PABP or nonpolyadenylated mRNAs

Outcome

mRNA stability and decay ratesurrogate

The poly(A)-PABP complex is a major determinant of mRNA stability in vitro, protecting polyadenylated mRNAs from indiscriminate destruction by cellular nucleases.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Should not change practice; extends in vitro evidence for PABP in mRNA stability but leaves cardiac translation open.
