Frameshift

Commonly, there are stimulatory signals in mRNA distinct from the shift site that greatly increase the level of frameshifting at the shift site.

Considering these costs, it seems likely that mechanisms may exist to stop frameshifted translation as soon as possible, depending on the frequency of occurrence.

Ribosomal frameshifting at a particular site can yield two protein products from one coding sequence or one protein product from two overlapping open reading frames.
