CC -!- FUNCTION: RECEPTOR FOR AN EXTRACELLULAR SIGNAL REQUIRED TO CC INSTRUCT A CELL TO DIFFERENTIATE INTO A R7 PHOTORECEPTOR. THE CC LIGAND FOR SEV IS THE BOSS (BRIDE OF SEVENLESS) PROTEIN ON THE CC SURFACE OF THE NEIGHBORING R8 CELL. CC -!- CATALYTIC ACTIVITY: ATP + A PROTEIN TYROSINE = ADP + CC PROTEIN TYROSINE PHOSPHATE. CC -!- SUBUNIT: MAY FORM A COMPLEX WITH DRK AND SOS. CC -!- SIMILARITY: BELONGS TO THE INSULIN RECEPTOR FAMILY OF TYROSINE- CC PROTEIN KINASES. CC -!- SIMILARITY: CONTAINS SEVEN FIBRONECTIN TYPE III-LIKE DOMAINS. CC -!- CAUTION: UNCLEAR WHETHER THE POTENTIAL MEMBRANE SPANNING REGION CC NEAR THE N-TERMINUS IS PRESENT AS A TRANSMEMBRANE DOMAIN IN THE CC NATIVE PROTEIN OR SERVES AS A CLEAVED SIGNAL SEQUENCE.
