Expression is restricted to adult stage. CC {ECO:0000269|PubMed:25688864}. CC -!- DISRUPTION PHENOTYPE: RNAi-mediated knockdown causes early larval CC arrest. In adults, results in no obvious phenotype. CC {ECO:0000269|PubMed:25688864}. CC -!- SIMILARITY: Belongs to the protein kinase superfamily. RIO-type Ser/Thr CC kinase family. {ECO:0000305}.
