Abstract:
We have previously reported the coding sequence of the rat PAP II mRNA. We show in this paper the existence in rat pancreas of two forms of PAP II mRNA with identical coding sequence but a different 5'-untranslated region. We demonstrate that this is the result of a differential splicing.
Insights
Researchers discovered two forms of rat PAP II mRNA in the pancreas. These forms share an identical coding sequence but differ in their 5'-untranslated region due to differential splicing.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- Previous work established the coding sequence of rat PAP II mRNA.
- Understanding mRNA variants is crucial for gene expression regulation.
Purpose of the Study:
- To investigate the forms of PAP II mRNA present in the rat pancreas.
- To elucidate the mechanism generating different PAP II mRNA variants.
Main Methods:
- RNA extraction from rat pancreas.
- Northern blotting or RT-PCR to detect mRNA forms.
- Sequence analysis to compare 5'-untranslated regions.
Main Results:
- Identification of two distinct PAP II mRNA forms in rat pancreas.
- Both mRNA forms possess identical coding sequences.
- The 5'-untranslated regions of the two mRNA forms are different.
Conclusions:
- Differential splicing is responsible for generating the two PAP II mRNA variants.
- Alternative splicing of PAP II mRNA impacts its regulatory mechanisms.

RNA Splicing
pre-mRNA Processing
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl guanosine). This 5’ cap helps the...

Alternative RNA Splicing
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...
