Chicken reticulocyte polysomal messenger RNA-protein complex: absence of bound proteins in most of the coding region of ß globln mRNA
Department of Biochemisny, University of North Carolina Chapel Hill, NC 27514, USA
Received April 18, 1984. Revised June 25, 1984. Accepted June 25, 1984.
The 15s globin mRNA-protein complex (mRNP) was isolated from chicken reticulocyte polyribosomes dissociated in EDTA. To determine protein binding sites, the mRNP was treated with micrococcal nuclease and the nuclease resistant RNA was mapped to the ß globin gene at the nucleotide level. As far as we can determine there is no bound protein from the Cap site to the poly A addition site of ß globin mRNA in the mRNP except for a short area in the coding region near the translation initiation site.
