These findings revealed an exonuclease involved in termination, and strongly support the “torpedo” model. Several studies have implicated RNApII pausing in termination [25–27]. Such pausing can be intrinsic to certain nucleotide sequences, but it can also be induced when RNApII is blocked by a DNA-binding protein or perhaps a particular chromatin feature. The torpedo model provides a satisfying explanation for these observations. Given that the RNApII continues transcribing past the poly(A) site, the Rat1 exonuclease must “catch up” to the elongation complex to trigger termination.
At the final stage of B-lymphocyte differentiation (plasma cells), however, the expression of CstF-64 is increased, and the weaker poly(A) site becomes recognized and utilized, resulting in the secreted form of IgM . Additionally, direct competition or interference of the CstF-64 binding to RNA by other RNA-binding proteins recognizing similar RNA sequences (U-rich) was also shown to affect the choice of poly(A) sites [113, 114]. Interestingly, many tissue-specific alternative poly(A) sites have suboptimal AGUAAA polyadenylation sequences [109, 115], and a UCUU element was often found to associate with brain-specific poly(A) sites .
KGaA. Published 2013 by Wiley-VCH Verlag GmbH & Co. KGaA. 1 The Allosteric Model This model suggests that RNApII becomes less competent for elongation when it reaches the poly(A) signal at the 3′ end of genes, perhaps due to an exchange of protein factors or a conformational change within the RNApII itself. It is clear that various proteins bind to RNApII only at certain stages of the transcription cycle and many of these dynamic transitions are mediated by the carboxy-terminal domain (CTD) of RNApII.
