Global Profiling of RNA-Binding Protein Target Sites by LACE-seq


ABSTRACT: Proteomic analysis of Ago2-/- oocytes revealed that Ago2 interacted with endogenous small interfering RNAs (endo-siRNAs) to repress mRNA translation globally.

RNA-binding proteins (RBPs) have essential functions during germline and early embryo development. However, current methods are unable to identify the in vivo targets of a RBP in these low-abundance cells. Here, by coupling RBP-mediated reverse transcription termination with linear amplification of complementary DNA ends and sequencing, we present the LACE-seq method for identifying RBP-regulated RNA networks at or near the single-oocyte level. We determined the binding sites and regulatory mech  ...[more]
