Sizing up the poly(A) tail: insights from deep sequencing
1Department of Biochemistry and Molecular Biology, Rutgers New Jersey Medical School, Newark, NJ 07103.
Abstract:
Global investigation of poly(A) tails has been hindered by technical challenges. In a recent advance, two groups developed deep sequencing methods to globally interrogate poly(A) tail length and sequence with high precision, opening new avenues for investigation of poly(A) tail functions in mRNA metabolism. Initial applications of these methods reveal insights into the relationship between poly(A) tail length and translational efficiency, and identify widespread uridylation and guanylation at the 3' ends of transcripts.
