Organism

Functioni

Probable receptor tyrosine kinase which is required for determination of anterior and posterior terminal structures in the embryo (PubMed:2927509, PubMed:8423783). During postembryonic development, involved in the initiation of metamorphosis probably by inducing the production of ecdysone in response to prothoracicotropic hormone Ptth (PubMed:19965758). Binding to Ptth stimulates activation of canonical MAPK signaling leading to ERK phosphorylation (By similarity).By similarity3 Publications

RNAi-mediated knockdown in the prothoracic gland (PG) delays the onset of pupariation by prolonging the L3 larval stage. In addition, pupal size and, to a lesser extent, PG cell size are increased.1 Publication
