HSFA2 Is Alternatively Spliced upon AZC Treatment.

The structural organizations of the two forms of the mature HSFA2 transcript are shown. In the HSFA2 mRNA, the single 324-nucleotide intron is removed. By contrast, the HSFA2-II RNA has an additional mini-exon (uppercase bold) included through the recognition of additional splice sites (lowercase) within the intron. The new stop codon is underlined. DBD, DNA binding domain; HR-A/B, oligomerization domain; NLS, nuclear localization signal; AHA, activation domain, notation taken from (Nover et al., 2001). Inverted triangle marks the position of the T-DNA insertion in the Arabidopsis insertional knockout (SALK_008978) line.
