| Enzyme Function | FUNCTION: Serine/threonine-protein kinase involved in sugar signaling during germination and seedling growth. Negative regulators of sugar response complex (SRC) in alpha-amylase gene promoters, thus relieving SRC sugar repression in a MYBS1-dependent manner. Required for MYBS1 and AAMY3 accumulation under glucose starvation. {ECO:0000269|PubMed:17766403}. |
