Refined Gene Model. TAIR locus AT1G63500 encodes a protein kinase. (A) Four novel peptides map within the 5′ UTR and the first exon. (B) Zoom of the region shows that the current first exon (frame 3) is out of frame with the peptides (frame 2). (C) Sequence alignment with Arabidopsis and grapevine proteins supports translation in the frame supported by peptides (observed peptides highlighted in alignment).
