Maps of SnRK1 Isoforms and Domain Structures. (A) The reported intron-exon maps of SnRK1 genes. Dark boxes denote exons while light boxes denote 5′ and 3′ UTRs. (B) SnRK1 kinases contain 3 domains: Protein Kinase, Ubiquitin Associated (UBA), and Kinase Associated 1 (KA1). The location of the active site residues are indicated by a purple circle.
