The Role of RNA Splicing and Post-Translational Proteolytic Processing in the Biosynthesis of Neuropeptides
The neuropeptides are synthesised by mechanisms which closely resemble those for other secreted proteins. Transcription of a neuropeptide gene results in the synthesis of precursor RNA which is processed in the nucleus into mature messenger RNA (mRNA). Only certain segments of the precursor RNA (exons) are present in mRNA and the remaining segments of RNA (introns) are excised during RNA maturation. In some cases, more than one species of mRNA may be generated from a single gene as the result of alternative patterns of RNA splicing.
