The clock-regulated RNA-binding protein AtGRP7 is part of a negative feedback circuit through which the protein influences circadian oscillations of its own transcript. Constitutive overexpression of AtGRP7 in transgenic plants leads to the appearance of a low amount of an alternatively spliced Atgrp7 transcript with a premature stop codon. It is generated by the use of a 5' cryptic splice site in the middle of the intron at the expense of the fully spliced mRNA, indicating a role for AtGRP7 in splice site selection.

Nicotiana plumbaginifolia UBP1 is an hnRNP-like protein associated with the poly(A)(+) RNA in the cell nucleus. Consistent with a role in pre-mRNA processing, overexpression of UBP1 in N. plumabaginifolia protoplasts enhances the splicing of suboptimal introns and increases the steady-state levels of reporter mRNAs, even intronless ones.
