Upon binding to its ligands, transduces the signal through the ras-raf-MAPK pathway and is involved in a myriad of developmental decisions (By similarity). Involved in the determination of adult size, ovary development, and development timing, especially during queen determination of honeybee larvae. May have an important role in the prolongation of longevity in queens. ATP + L-tyrosyl-[protein] = ADP + H(+) + O-phospho-L-tyrosyl-[protein] Activated by MRJP1 during queen determination of honeybee larvae. Reduced adult size and ovary size, and prolonged developmental time. Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily.
