Extensive Structural Differences of Closely Related 3′ mRNA Isoforms: Links to Pab1 Binding and mRNA Stability

Expression of RFamide-Related Peptide-3 (RFRP-3) mRNA in Dorsomedial Hypothalamic Nucleus and KiSS-1 mRNA in Arcuate Nucleus of Rat during Pregnancy

An interaction between two RNA binding proteins, Nab2 and Pub1, links mRNA processing/export and mRNA stability.

mRNA stability is modulated by elements in the mRNA transcript and their cognate RNA binding proteins. Poly(U) binding protein 1 (Pub1) is a cytoplasmic Saccharomyces cerevisiae mRNA binding protein that stabilizes transcripts containing AU-rich elements (AREs) or stabilizer elements (STEs). In a yeast two-hybrid screen, we identified nuclear poly(A) binding protein 2 (Nab2) as being a Pub1-int...

An mRNA stability complex functions with poly(A)-binding protein to stabilize mRNA in vitro.

The stable globin mRNAs provide an ideal system for studying the mechanism governing mammalian mRNA turnover. alpha-Globin mRNA stability is dictated by sequences in the 3' untranslated region (3'UTR) which form a specific ribonucleoprotein complex (alpha-complex) whose presence correlates with mRNA stability. One of the major protein components within this complex is a family of two polycytidy...

Links between mRNA splicing, mRNA quality control, and intellectual disability.

In recent years, the impairment of RNA binding proteins that play key roles in the post-transcriptional regulation of gene expression has been linked to numerous neurological diseases. These RNA binding proteins perform critical mRNA processing steps in the nucleus, including splicing, polyadenylation, and export. In many cases, these RNA binding proteins are ubiquitously expressed raising key ...

P-222: Expression of RFamide-Related Peptide-3 and KiSS-1 mRNA in The Hypothalamus of Pregnant Rat

Background: There is no follicular development during pregnancy in the rat comparable to the changes of the estrous cycle. RFamide-related peptide-3 (RFRP-3) and kisspeptin were recognized as regulator of gonadotropin releasing hormone (GnRH) and luteinizing hormone (LH) secretion in several species, including the rat. The aim of the present study was to evaluate the relative expression of RFRP...
