SR45a. Heat-induced differential splicing of Arabidopsis gene SR45a (AT1G07350) encoding an RNA-binding protein involved in splicing. Tracks labeled Hot and Cool contain exon-exon junction features inferred from spliced read alignments from heat-treated (hot) and control samples (cool). Junctions with fewer than five supporting reads are not shown. Two annotated gene models for SR45a are shown in the track labeled TAIR 10 mRNA. Taller blocks indicate translated regions of the gene model. Note that inclusion of an internal exon introduces a premature stop codon that interrupts translation and the exon-skipped form likely encodes the full-length protein. The gene is on the minus strand of chr1 and so transcription proceeds from right to left.
