MRNAs associated with human PUM1 protein

ABSTRACT: To identify mRNAs associated with human PUM1 protein, we used a modified Ribonucleoprotein-ImmunoPrecipitation Microarray (RIP-Chip) approach on HeLa S3 cancer cells that express PUM1. PUM ribonucleoprotein (RNP) complexes were captured from cell-free extracts with anti PUM1 specific antibody Bethyl Laboratories, #300-201A coupled to protein G (PUM1) sepharose beads, and then eluted with SDS-EDTA. To control for non-specifically enriched RNAs, the same procedure was performed with beads that were not coupled with immunoprecipitating antibody (mock samples). Total RNA was isolated from cell extracts and immunopurified samples with the mirVanaTM PARISTM kit (Ambion). RNA was quantified with a NanoDrop device (Witeg AG). Poly-adenylated RNAs were amplified in the presence of aminoallyl-UTP wi
