RA3

Gene
RA3
Protein
Trehalose 6-phosphate phosphatase RA3
Organism
Zea mays
Length
361 amino acids
Function
Removes the phosphate from trehalose 6-phosphate to produce free trehalose. Is specific for trehalose 6-phosphate. Does not possess activity toward glucose, sucrose or fructose 6-phosphates. Regulates inflorescence branching. Required to establish the correct identity and determinacy of axillary meristems in both male and female inflorescences. May acts through a sugar signal that moves into axillary meristems. Acts upstream of RA1. May have a transcriptional regulatory function.
Similarity
Belongs to the trehalose phosphatase family.
