Shaping the Arabidopsis Transcriptome through Alternative Splicing

Figure 2

Consequences of alternative splicing. (a) Scheme of a pre-mRNA with two mutually exclusive exons. Alternative splicing leads to a protein variant retaining exon2 (top) or exon 4 (bottom). The resulting proteins have different domain structures. (b) Scheme of a pre-mRNA with alternative 3′ splice sites at intron 2. The use of the alternative 3′ splice site leads to retention of part of the intron with a premature termination codon. The resulting splice variant can be subject to nonsense-mediated decay.
