RNA 5' Terminal Oligopyrimidine Sequence
"RNA 5' Terminal Oligopyrimidine Sequence" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus,
MeSH (Medical Subject Headings). Descriptors are arranged in a hierarchical structure,
which enables searching at various levels of specificity.
A regulatory sequence found in the 5' terminal regions of a variety of RNA species. The sequence starts with a CYTIDINE, which is followed by a stretch of 5 to 15 PYRIMIDINE NUCLEOTIDES. Messenger RNA that contains the 5' Terminal Oligo Pyrimidine tract is often referred to as 5' TOP mRNA. The sequence acts as a translational regulator and has been found in mRNAs for PEPTIDE ELONGATION FACTORS and RIBOSOMAL PROTEINS.
