Protein: DDB1- and CUL4-associated factor 12 homolog (Q9VGE3)
Organism: Drosophila melanogaster (Fruit fly)
Function: Substrate-recognition component of a DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complex, which mediates ubiquitination of target proteins, leading to their degradation. Required for synaptic function and plasticity at larval neuromuscular junctions (NMJs) by promoting neurotransmitter release. The DCX(DCAF12) complex catalyzes ubiquitination and degradation of yorkie (yki), thereby regulating the Hippo/SWH (Sav/Wts/Hpo) signaling pathway. Acts as a regulator of tissue growth during development: required for the apoptotic elimination of supernumerary cells during metamorphosis.
