Protein
Serine/threonine protein kinase OSK1
Organism
Oryza sativa subsp. japonica
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.
Similarity
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
