mRNA Splicing: Regulated and Differential

Abstract

Alternative splicing is the process by which single genes express multiple messenger RNAs (mRNAs), and therefore multiple proteins, by differential processing of the primary transcript (pre‐mRNA). The temporal and spatial regulation of protein expression by alternative splicing is determinative for such diverse biological processes as gender specification in Drosophila, commitment to apoptosis, and sound frequency recognition of individual hair cells in the avian cochlea.

Keywords: alternative splicing; pre‐mRNA; cell‐specific regulation

Figure 1.

Alternative splicing regulates Drosophila sex determination. The male (black) and female‐specific (red) splicing patterns are indicated. The six 13‐nt repeats in the dsx female‐specific exon are indicated in light blue. A purine‐rich element is indicated in black.

Figure 2.

Alternative splicing pathways of vertebrate experimental systems. Alternative exons are indicated in red. Regulatory elements are indicated in light blue.
